Question

How do you calculate concentration from titration?

Answer 1

Using, $M_A{V}_A=M_B{V}_B$

Let's assume you are titrating a strong acid $(10mL$ unknown concentration $HCl)$ with a strong base $\left(1.0MNaOH\right)$. It takes $25mL$ of $NaOH$ to neutralize the acid.

$M_A=\frac{M_B{V}_B}{V_A}$

or $M_A=\frac{1.0M\times 25mL}{10mL}$

$M_A=2.5MHCl$

Thus we can calculate the concentration from titration.
