When will acids react with metals? |
Acids will react with metals that are above hydrogen in the reactivity series. |
|
|
Why don't we react acids with very reactive metals? |
We don't react acids with very reactive metals such as sodium and potassium because the reactions are too violent to be done safely. |
|
|
What happens when metals react with acids? |
When metals react with acids they produce salt and hydrogen gas. |
|
|
How can salts be crystallised from solutions? |
Salts can be crystallised from solutions by evaporating off water. |
|
|
What happens when a acid reacts with a base? |
When a acid reacts with a base a neutralisation reaction happens and a salt and water are produced. |
|
|
How are soluble salts made? |
Soluable salts are made by reacting acids with metals, insoluble bases or alkalis. |
|
|
How is salt produced from a insoluble base? |
Salts is produced from a insoluble base --- the base is added to the acid until no more will react and the excess solid is filtered off. Leaving a solution of salt. |
|
|
Why do we add excess of a base when making salt. |
To use up all the acid or to neutralise all the acid. |
|
|
What are chlorides made from? |
Chlorides are made from hydrochloric acid. |
|
|
What are nitrates made from? |
Nitric acid. |
