Question

1. write equations for the decomposition of h₂co₃ and h₂so₃.
2. at what temperature (from your graph) do kno₃ and nacl have the same molar solubility?

Explanation:

Step1: Write decomposition equation for $H_2CO_3$

$H_2CO_3
ightarrow H_2O + CO_2$

Step2: Write decomposition equation for $H_2SO_3$

$H_2SO_3
ightarrow H_2O+SO_2$

Step3: Regarding question 4, since no graph is provided, cannot solve. But in general, find intersection point on solubility - temperature graph.

Answer:

1. $H_2CO_3

ightarrow H_2O + CO_2$, $H_2SO_3
ightarrow H_2O+SO_2$

1. Cannot be determined without graph.
