WebHere, the equation is: HCl + NaOH --> NaCl + H 2 O. From the equation we can see that there is a 1:1 ratio between the acid and alkali, so if we have 0.03 mol of NaOH then we also have 0.03 mol of HCl. Now that we know the moles and volume of HCl, we can work out its concentration. 0.03 / (60/1000) = 0.5 mol dm 3.
