Column 3 has the names of gases to be prepared using the substance you enter in column 1, along with dilute or concentrated sulphuric acid, as indicated in column 2.
| Column 1 | Column 2 | Column 3 |
| Substance reacted with acid | Dilute or concentrated sulphuric acid | Gas |
| Hydrogen | ||
| Carbon dioxide | ||
| Only chlorine |
Write the equation for the laboratory preparation of :
(i) Sodium sulphate using dilute sulphuric acid.
(ii) Lead sulphate using dilute sulphuric acid.
Solution
| Column 1 | Column 2 | Column 3 |
| Substance reacted with acid | Dilute or concentrated sulphuric acid | Gas |
| Metal | Dilute sulphuric acid | Hydrogen |
| Carbonate | Dilute sulphuric acid | Carbon dioxide |
