Question

234. Five solutions A,B, C, D and E when tested with universal indicator show pH as 5, 1,12 ,7 and 9 respectively. Which solution is

(b) Weakly basic

Answer 1

• Solutions which have a pH range from 0 to 7 are termed as acids.
• Solutions which have a pH range from 7 to 14 are termed as bases.
• Solutions which have pH value 7 are termed as neutral solutions.
• The more acidic the solution, lower will be its pH .
• Basicity of a solution increases with increase in its pH value.
• Here, the solution E which has a pH value of 9 will be weakly basic.
• Hence, the solution E is weakly basic.
