Q4. 10.0 mL of a mixture solution of NaCl & KCl titrated against 36.0 mL of 0.04 M AgNO3 solution to get the end of chromate indicator. If you know that each 1 L of the mixture solution contain 10 g of (of NaCl + KCl). Calculate the concentration of NaCl and KCl in the mixture solution. (M. mass of NaCl =58.5 g/mol, KCl = 74.5 g/mol).

(5 points) select one: a. it is a salt because it increases the concentration of metallic ions. b. it is a salt because it is formed by the reaction of an acid and a base. c. it is an acid because it increases the concentration of hydroxyl ions. d. it is an acid because it increases the concentration of hydronium ions.
