Question

You have been asked to organize the following aqueous solutions: HCl, NaOH, H2SO4,Ca(OH)2, LiOH, and HCIO3.How would you group them?On what are you basing your decision?

Answer 1

The easiest way to classify them is by separating into acids and bases.

$\boxed{\begin{array}{c|c}\boxed{\bf{Acids}} &\boxed{\sf Bases}\\ &\\ \sf HCl &\sf NaOH\\ &\\ \sf H_2SO_4 &\sf Ca(OH)_2 \\&\\ \sf HClO_3 &\sf LiOH\end{array}}$

Note it down

• Acids give H+ ions and Bases give OH- ion while mixed up with water
