Chapter 18.1, Problem 2PP

Interpretation Introduction

Interpretation:

The ionic form of given equation is to be written.

Concept introduction:

Ionic equation can be written by written the ionic compounds in ionic form on both sides and then balancing the equation.

Answer to Problem 2PP

$C{O}_3{}^{2-}+2H^{+}\to H_{2}O+C{O}_2$

Explanation of Solution

The given equation is:

$CaC{O}_3+2HBr\to CaB{r}_2+H_{2}O+C{O}_2$

Writing the ionic compounds in ionic form:

$C{a}^{2+}+C{O}_3{}^{2-}+2H^{+}+2B{r}^{-}\to C{a}^{2+}+2B{r}^{-}+H_{2}O+C{O}_2$

Thus balanced equation is:

$C{O}_3{}^{2-}+2H^{+}\to H_{2}O+C{O}_2$

Conclusion

Thus the given equation in ionic form is:

$C{O}_3{}^{2-}+2H^{+}\to H_{2}O+C{O}_2$
