Question

A 25,0ml sample of 0,105M HCl was tritrated with 31,5ml of NaOH.what is the concentration of the NaOH?
millimols HCl = mL x M = ?
millimols NaOH used = mmols HCl since 1 mol HCl = 1 mol NaOH in the equation.
Then M NaOH = mmols/mL = ?

The equation is HCl + NaOH ==> NaCl + H2O

Post your work if you get stuck.
