Question

Find the concentration of HCL, if 10ml of 05M Ca(OH)2 is required to titrate 50ml of HCl.

Answer 1

The molarity of HCl can then be calculated as: Molarity = Moles / Volume(L) = 0.01 moles / 50/1000 L = 0.2 M = 1/5 M So, the concentration of HCl is 1/5 M, which corresponds to option (d).
