Question

10. Why do we store silver chloride in a dark colouredbottle?
11. Why do we add a few drops of dilute sulphuricacid to water prior to electrolysis?​

Answer 1

Answer:

10.AgCl3 is stored in dark coloured bottles because it reacts with sunlight to decompose and form chlorine gas.

11.Pure water is a non-conductor of electricity. Tap water cannot be used in electrolysis as it contains impurities which may travel to cathode. So water is acidified by adding H2SO4 in it which is also an example of catalysis.
