Question

A, B, C, D are samples of liquids having pH values of 14, 7, 1, 5 respectively. Which of these could be that of NaOH solution? a.Sample D b.Sample C c.Sample A d.Sample B

Answer 1

Answer:

sample A

are the samples of liquid having on values of 14,7,1,5 respectively...

Answer 2

c. Sample A could be that of NaOH solution.

• Sodium hydroxide is a strong base, as it completely dissociates into the solution. The high basic strength will be shown at high range of pH. The pH 14 will be highly basic solution.
• The pH 7 represents neutral nature of solution.
• At pH 5, the solution will be mildly acidic.
• At pH 1, the solution will be highly acidic.
• The range of pH scale is from 0 to 14. The increase in pH states increase in hydroxyl ion concentration and decrease in hydronium ion concentration.
