Title: What volume of sodium hydroxide is needed to completely neutralise nitric acid?
Post by: tony3320 on Feb 15, 2013
What volume of sodium hydroxide solution having a concentration of
0.1 mol dm-3 is needed to completely neutralise 50 cm3 of 0.75 mol dm-3
aqueous nitric acid?

HELP PLEASEEE
Thanks in advance, it is much appreciated.

NaOH + HNO3 = NaNO3 + H2O

moles of HNO3 = .75 x 50 / 1000 = .0.0375  = moles of NaOH from the equation
volume of NaOH with these moles = number of moles / molarity
= .0.0375 / .1 =.375 / .1  liters or 375 mL
