c) why dowe store silver chloride in dark bottle?​

Answer 1

Answer:

1 - Small amount of acid is added a water during electrolysis of of water

Becuase distilled water does not conduct electricity and there are no free electrons

but when we add the acid it dissociate and charge flows into the water

2 - When ammonium chloride is dissolved in water in a test tube the test tube become cold

Because the reaction occured here is endothermic
