it is found that 23.8 ml of 1 x 10^-3 M Sr(OH)2 is required to titrate 10.0 ml of an HCl soln.
A) what is the concentration of the HCl soln?
B) what is the pH of the HCl soln?
Sr(OH)2 + 2HCl --> SrCl2 + 2H2O
moles Sr(OH)2 = M x L = ??
moles HCl needed = 2*moles Sr(OH)2 [from the equation].
M HCl = moles/L solution.
