Acids and bases test
| Question | Answer |
|---|---|
| Acids | Substance that produces a hydronium ion (H3O+)when dissolved in water |
| Base | Substance that produces hydroxide ions (OH-) when dissolved in water |
| pH | An inverse measure of the concentration of hydronium ions (H3O+) in a solution |
| Indicator | Compound that changes color at different pH values when it reacts with acidic or basic solutions |
| Acids on a pH scale | 0-6 |
| Bases on pH scale | 8-14 |
| 2 examples of acid and chemical equations | Acetic acid:CH3COOH Lactic acid: C3H6O3 |
| 3 properties of acids | -Sour taste in food Most can damage skin and eyes |
| Where can Acids be found? | Soft drinks, tomatoes,lemon juice |
| 2 examples of bases and chemical formula | Ammonia:NH3 Sodium hydroxide:NaOH |
| 3 properties of bases | -bitter taste in food - slippery when in water |
| Where can bases be found | Ammonia,detergent, blood |
| 3 ways to measure pH | pH indicators, pH testing strips and pH meters |
| Ammonia base chart | Ammonia (NH3)+ Water(H20)-> Ammonia (NH4)+Hydronium Ion (OH-) |
| Acid chart | Hydrochloric Acid (HCL) +H20 water -> Hydronium ion (H30+)+ Chlorine ion (Cl+ |
