level questions: Soluble Salts + PH scale
| Question | Answer |
|---|---|
| What are soluble salts | salts which dissovle in water |
| How can we produce salts | a reaction between acids and solids(metal oxides, hydroxides, carbonate also pure metals) |
| What are the two main ways of measuring the PH of a substance | 1) PH probe which returns a number to represent the PH of a solution 2) Universal indicator which changes colour depending on the PH of a solution |
| What is the numerical PH scale a measure of | the concentration of H+ ions in a solution |
| What happens to the concentration of H+ ions for every increase in 1 PH with examples | Gets divided by 10 e.g. PH 0 = concentration of 1mol/dm3 PH1 = concentration of 0.1mol/dm3 PH 2 = concentration of 0.01mol/dm3 |
