Question

Give reason why : (a) Na acts as an reducing agent
while chlorine acts as an oxidising agent in the
reaction : 2Na(s) + Cl2 (g) → 2NaCl(s)
(6) White coloured AgCl turns grey when kept in
sunlight.
(c) Colour of the solution changes when iron nail is
dipped in copper sulphate solution.
(d) Lime water turns milky when CO2 is passed through it ?​

Answer 1

Answer:

because in the reaction Sodium loses an electron and get oxidized whereas chlorine gain an electron and get reduced.

because it decomposes into silver, which is greyish in colour and chlorine

as iron is more reactive than copper, it displaces copper from its sulphate solution and form its own solution

lime water turns milky when CO2 is passed through it because of the formation of calcium carbonate which gets soluble
