How many milliliters would it take to titrate 10.0 mL of 0.75 M HCl with 0.10 M NaOH?

Answer 1

Start from the equation

NaOH + HCl -> NaCl + H2O

so 1 mole of HCl is needed for each mole of NaOH

So mmoles of HCl are

10.0 ml x 0.75 mol l^-1

which must be equal to number fo mmoles of NaOH used

X ml x 0.10 mol l^-1

solve for X
