Chapter 8.2, Problem 30PP

Interpretation Introduction

Interpretation:

The formula of carbonic acid needs to be determined.

Concept introduction:

1. The names of binary acids (acids containing hydrogen and one more element) are given by adding prefix hydro- and suffix $-ic$ to name of higher electronegative radical.
2. The names of acids containing radicals or polyatomic groups are given on basis of second element but prefix hydro- is not used.

Answer to Problem 30PP

Carbonic acid is $H_{2}C{O}_3.$

Explanation of Solution

The charge on H atom is +1 and that on carbonate is 2-.

I: $H^{1+}C{O}_3{}^{2-}$

II:

III: Formula $H_{2}C{O}_3$

Conclusion

Carbonic acid is common name of $H_{2}C{O}_3.$
