Question

What volume of 0.100 M HCl solution is needed to neutralize 25.0 mL of 0.350 M NaOH?

Answer 1

you first wanna write an equation for the reaction:

\(HCl + NaOH \rightarrow H_2O+NaCl\)

you'll notice that their stoichiometric ratio is 1:1

thus moles of acid = moles of base

so just use: \(M_1V_1=M_2V_2\)

Answer 2

oooh okay! thanks
