When you mix vinegar and baking soda you get a chemical change. The chemical property that causes this is called reactivity. Baking soda’s chemical formula is NaHCO3 and it’s a compound. Vinegar’s chemical formula is CH3COOH and it’s a compound. The problem of this is how much baking soda‚ added to 10mL of vinegar‚ will cause a film canister rocket to shoot the furthest. I think 5mL will shoot the farthest because there will be more for the baking soda build up in the canister. The independent variable

These are ammonia‚ vinegar; drain cleaner‚ soft drink‚ baking soda‚ detergent‚ and lemon juice are the solutions that are going to be tested in this lab. My hypothesis for these solutions is ammonia is acid‚ vinegar is neutral‚ drain cleaner is base‚ soft drink is base‚ baking soda is base‚ detergent is base‚ and lemon juice is an acid. For the red cabbage it would

an enzymes that speeds up the production of cheese. 3. First milk is pasteurized by heating it to 72℃ for 15 seconds to kill any harmful bacteria. Then‚ the milk is cooled and either a special blend of bacteria or an acidic solution - such as vinegar or lemon juice - is added. The milk is left for one and half hours while the bacteria converts lactose (a substance called "milk sugar") into lactic acid. This causes the milk to sour and the pH to drop to approximately 4.5. A substance called "rennet"

facilitated diffusion‚ filtration‚ and osmosis. In our Osmosis Lab I used a Grade a large egg from the grocery store. Its circumference is 5 ½ inches it is smooth with no cracks. I carefully place the egg in a clear plastic cup and fill the cup with vinegar. I immediately notice bubbles covering the egg and sifting upwards towards the top of the cup‚ looking through the cup I can see the egg is slightly suspended in the liquid. Within 25 hours there was white foam covering the egg. I cannot see the egg

Determining pH Using a Red Cabbage Farnoosh Mazarei Food Microbiology April 22‚ 2011 Purpose: To test the pH level of many common household object by use of the juice from a red cabbage. Background: pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 with 1 through 6 being acidic and 8 through 14 being basic; 7 is considered neutral. The use of the red cabbage‚ or red cabbage juice is because red cabbage can be used as an acid/base indicator
