Name the dilute acid that must be present in order to test for sulfate ions with barium chloride.

Sulfate ions can be tested for using a dilute acid and which other solution?

Describe what is observed when magnesium and barium are reacted separately with anexcess of dilute sulfuric acid

) Instead of dilute sulphuric acid, dilute hydrochloric acid is taken

Describe a chemical test to show that the sodium chloride solution containschloride ions.
