If the resistance of the same cell when filled with 0.02 mol L-1 KC1 solution is 520 Q, calculate the conductivity and molar conductivity of 0.02 mol L KC1 solution. The conductivity of 0.1 mol L 1.29 X 10 -2 CT1 cm -1 Answer: (a) Refer Ans. to Q.23. If we raise the temperature somewhat, all the KCl will dissolve, but on cooling to 25°C again, the extra 0.5 g KC1 will precipitate, leaving exactly 35.5 g of the salt dissolved. We describe this phenomenon by saying that at 25°C the solubility of KCl in H 2 O is 35.5 g KC1 per 100 g H 2 O.Answer to Solved When heated, (ce{KCIO3}) decomposes into (ce {KC1})
