If 5.00 mL of HCl require 4.59 mL of 0.9581 M NaOH to just consume the HCl, what is the concentration of the HCl?
3 answers
.9581*4.59=X then X/5 = .8795 which is the concentration
Write the equation, and see it is 1:1
HCl + NaOH ==> NaCl + HOH
Since it is 1:1 (and ONLY then), you can use mL x M = mL x M. Solve for the one unknown.
