How many liters of water must be added to 1 liter an aqueous solution of HCl with a pH of 1 to create an aqueous solution with pH of 2?
Text Solution
Verified by ExpertsThe correct answer is:
D
pH = 1 [H + ] = 10 –1 = 0.1 M
pH = 2 [H + ] = 10 –2 = 0.01 M
for dilution of HCl M 1 V 1 = M 2 V 2
0.1 × 1 = 0.01 × V 2 V 2 = 10 lt
Volume of water added = 10–1 = 9 liter
