Interpretation Introduction

To identify: Each of the following as an acid or base.

  1. H2SO4
  2. RbOH
  3. Ca(OH)2
  4. HI

Answer to Problem 10.71UTC

Solution:

  1. H2SO4 − Acid.
  2. RbOH − Base.
  3. Ca(OH)2 − Base.
  4. HI − Acid.

a. Given: H2SO4

Explanation of Solution

According to Arrhenius concept, substance that dissociates in water to give H+ ions or increases the concentration of H+ ions is said to be acidic in nature.

So, H2SO4is an acid as it gives H+ ions in aqueous solution.

b. Given: RbOH

According to Arrhenius concept, substance that dissociates in water to give OH- ions or increases the concentration of OH- ions is said to be basic in nature.

So, RbOH is a base as it gives OH- ions in aqueous solution.

c. Given: Ca(OH)2

According to Arrhenius concept, substance that dissociates in water to give OH- ions or increases the concentration of OH- ions is said to be basic in nature.

So, Ca(OH)2is a base as it gives OH- ions in aqueous solution.

d. Given: HI

According to Arrhenius concept, substance that dissociates in water to give H+ ions or increases the concentration of H+ ions is said to be acidic in nature.

So, HI is an acid as it gives H+ ions in aqueous solution.

Conclusion

Thus H2SO4 and HI are acids whereas RbOH and Ca(OH)2 are bases.
