Take it off to see if the drain is now okay; if the clog is still there‚ repeat the steps until it’s dislodged. Achieve victory with vinegar (and baking soda) You probably already know that vinegar is good for cleaning mirrors and refrigerator shelves. Its talents don’t stop there‚ though‚ since it can also remove clogs when paired with baking soda. If you’re ready to start‚ here are some of the steps you must take: 1. Ensure the sink or tub is completely dry. If it has standing water‚ scoop

On this lab we used 7 different solutions to determine if it’s either base‚ acid‚ and neutral. 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 be the same as using red and blue

Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited reactants. It is hypothesized that the limited reactant of this experiment is the baking soda. Materials- * 2

Lesson: This should be presented as a chemistry experiment. Ask the kids what a chemical reaction is? Did they know they can make gasses out of liquids or solids? What happens if they put things like baking soda and vinegar together? If they don’t know‚ tell them the two create a gas when combined. What’s gonna happen if you combine
