Question

What is the concerntration of 10.00ml of HBr if it takes 16.73ml of a 0.253M LiOH solution to neutralize it

Answer 1

First Find moles of LiOH (.235 moles/L X .01673L) You have .00423269 moles of LiOH. The Equation is written (HBr +LiOH -> LiBr + H2O), 1;1 Ratio. We find the molarity of HBr (.00423269 moles / .01 L). We are left with .42M HBr.
