Double-Acting and Single-Acting Baking Powder

If youre like me, youre lucky to pay enough attention to a recipe to notice whether youre supposed to be using baking powder or baking soda. Both ingredients cause baked goods to rise—but they are not interchangeable (although you can swap them out as long as you know what youre doing). Theres also more than one type of baking powder. Since you can find both single-acting baking powder and double-acting baking powder, youre probably wondering how theyre different and whether or not you should use half as much double-acting baking powder as single-acting baking powder. Whats the Difference? For any recipe that calls for baking powder, you should use exactly same amount of double-acting baking powder as you would single-acting baking powder. The difference between the two types of powder is their chemical composition. One produces the carbon dioxide gas bubbles that make your baked goods rise when the ingredients are mixed, while the other produces them when the product is heated in the oven. Even though theyre different, both types of baking powder produce the same amount of gas, so theyre equally effective as leavening agents. Single-acting baking powder reacts with a water-based ingredient to form bubbles as soon as the ingredients are mixed. If you wait too long to bake your food or over-mix your ingredients the bubbles will escape and your food will fall flat.Double-acting baking powder produces some bubbles when the ingredients are mixed, however, most of the rising occurs once it meets the heat. Double-acting baking powder is more reliable for home baking because it is harder to overbeat the ingredients and your recipe will be less susceptible to failure should you forget to preheat your oven. Because its practically foolproof, this is the type of baking powder most often found in stores. You most often encounter single-acting baking powder in commercial applications. Its also the type of baking powder youd be making if you wanted to try to prepare baking powder yourself.

Unknown Mixtures Lab Report Free Essays

-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt, sugar, dirt, and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it, pouring water, vinegar, and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First, do steps (3-6)to find out the properties of salt, sugar, dirt, and baking powder. We will write a custom essay sample on Unknown Mixtures Lab Report or any similar topic only for you Order Now 3) Observe and record the appearances of the four known substances. ) Burn the known substances one by one to see what will happen. When it starts to burn take the beaker off of the burner. 5) Add water to all substances. Make sure to stir well (until the salt and sugar dissolve) to see how each substance reacts with water 6) Add vinegar to all substances. Make sure to stir well (until the salt and sugar dissolve) to see how each substance reacts with vinegar 7) Observe your unknown substance and write down how it looks 9) Add water to the unknown substance. Check to see if it turns to mud and that the white substance dissolves. 10) Heat up unknown substance until it starts to burn. Check and see if the substance starts to turn brown and smell good and dry up and crack. This is to see if the unknown substance is a combination of dirt and sugar. Safety Precautions- * Remember to wear closed shoes just in case someone drops something like glass and it lands on your foot. * Always wear goggles, and for girls tie their hair, when near a burner so it doesn’t burn your hair or get something in your eye. Be careful not to drop the beakers so that there will be no danger of accidently stepping on glass. Observations- The sugar turned brown and smelled good when heated, salt turned black and smelled like burnt rubber when heated, dirt turned to mud when water was added, and baking soda started to bubble when vinegar was added. DATA: TABLE 1: CHARACTERISTICS OF SUBSTANCES SUBSTANCE| Characteristics| Appearance | Sugar| Heat: sugar turns bro wn and smells goodWater: sugar dissolvesVinegar: sugar dissolves| White, shiny, looks similar to sugar. Salt| Heat: turns black, smells like burnt rubberWater: dissolvesVinegar: dissolves| White, looks like sugar except it isn’t shiny| Dirt| Heat: dries up and starts to crackWater: turns to mudVinegar: turns to mud| Brown, has bits of rock and dried grass in it| Baking Soda| Heat: Water: turns water whiteVinegar: starts to bubble | White, soft, kind of like flour| These are some of the characteristics and appearances of the four known substances after experimenting (heating, adding water, adding vinegar, observing) to find their properties. This will help when trying to figure out the two substances in the unknown mixture. TABLE 2: UNKNOWN SUBSTANCE Substance| Characteristics| Appearance| Result| Unknown| Water: the substance turned to mud and the white specks dissolvedHeat: while the dirt turned hard, the white substance started to turn brown and smell good | * pieces of rock and dried and grass * small white shiny specks mixed in | Dirt and Sugar| This is the data collected from observing the unknown substance. From looking at table 1 and then comparing the appearance of the known substances to the unknown substance the unknown substance is the most similar to the appearances and characteristics of dirt and sugar. DATA ANALYSIS: The data collected states all the characteristics and appearances of the four known substances. This helps when trying to find the two substances in the unknown mixture. To gather the data the substances were burned, added with water and vinegar, and observed. Then with the information of the known substances was compared with the characteristics of the unknown substances. The unknown substance had characteristics similar to dirt and sugar, and so the unknown substance was experimented to check if they were really dirt and mud by adding water to see if it turned to mud and heating the substance to see if it would turn brown and smell good. CONCLUSION/ EVALUATION/IMPROVEMENTS: The purpose of this experiment was to find out the two substances of the unknown mixture out of salt, sugar, dirt, and baking soda. For this experiment my hypothesis was correct. The purpose of this experiment was achieved by observing and finding out the characteristics of each substance. The sugar turned brown and smelled good when heated, salt turned black and smelled like burnt rubber when heated, dirt turned to mud when water was added, and baking soda started to bubble when vinegar was added. According to table 1 the data shows that the unknown substance had similar characteristics to both sugar and dirt. And so to find out if my hypothesis was correct or not experiments were carried out based on tests that were characteristics of either sugar or dirt. One experiment was heating the unknown substance to check if it would start drying up and bubbling brown. The other was adding water to test if it would turn into mud. Some mistakes that could be improved in the experiment next time is- making sure not to pour a lot of salt into the beaker when heating it, since there was a lot of salt when heating it the smell was more nastier and shocking. Also when heating the dirt not to let it burn for a long time because when washing it, it was hard to get some of the dirt off. How to cite Unknown Mixtures Lab Report, Papers
