25.0cm³ of sodium hydroxide are neutralised by 15.0cm³ of hydroclauric acid with a concentration of 0.100mol/l. Find the concentration of the sodium hydroxide solution.
1. Start by writing the recation equation: NaOH + HCl --> NaCl + H20
(This tells us that 1 mole of NaOH neutralises 1 mole of HCl)
2. Now, work out the amount of moles of the…
