Question
Write the formulae of sodium chloride and sodium carbonate.
Solution
The formula of sodium chloride is NaCl and that of sodium carbonate is Na2CO3.
An aqueous solution of sodium chloride is neutral because sodium chloride is formed from a strong acid, hydrochloric acid (HCl), and a strong base, sodium hydroxide(NaOH). When sodium chloride is dissolved in water, it gets hydrolysed to give equal amounts of hydroxide and hydrogen ions, and this makes its aqueous solution neutral.
