Acids and Bases
| Question | Answer |
|---|---|
| Name three different everyday Acids | Lemon juice, Rainwater, and Vinegar |
| Name two laboratory Acids | Hydrochloric acid and Sulfuric acid |
| Name three everyday Bases | Toothpaste, Bleach, and Indigestion tablets |
| Name three laboratory Bases | Sodium Hydroxide, Calcium Carbonate, and Potassium Hydroxide |
| Name two different indicators | Litmus Paper and Universal Indicator |
| What happens when blue litmus is placed in acid | Turns Red |
| What happens when red litmus is placed in a base | Turns Blue |
| what happens to litmus paper in neutral | Nothing changes |
| What is pH 1 equal to | Highly Acidic |
| What is pH 14 equal to | Highly Alkaline |
| What is pH 7 equal to | Neutral |
| What is always produced in reactions of Acids | Salt |
| What is the word equation between Acids and Metals | Metal + acid →salt + hydrogen |
| How do you name the salt produced by the reaction between Acids and Metals | when naming the salt the first part is the name of the metal (e.g. zinc) and the second is based on the acid used (e.g. hydrochloric acid). Zinc + hydrochloric acid zinc chloride + hydrogen |
| How do you Test for Hydrogen | you must place a lighted splintinto the test tube |
| How do you Neutralise an Acid | You must put a Base into the Acid |
| How do they react together | They become water and salt |
| What happens when you mix Sodium Hydroxide and Hydrochloric Acid | It becomes salt and water |
| What happens to Laboratory Acids when mixed with water | The acid breaks up its elements |
| What happens to hydrochloric acid when mixed with water | The Hydrogen and Chlorine seperate |
| What happens to a Base in water | It seperates |
| What happens if you mix a Base water and a Acid water | the seperated acid particles join with the bases to make another two substances |
| What does Titration allow | Titration allows you to find out how much acid is needed to neutralise a base |
| What is Titration | Titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution |
