How does the solubility of all "ionic solids" change with an increase in temperature? Explain. 15. How does the solubility of all "gases" (NH), SO2 and HCI) change with increased temperatures? Explain at the particle level the cause of the change in solubility oef en

please answer all

Answer 1

In the graph x-axis represent temperature and y axis represent the amount of solute to be mixed in 100g of water to obtain a saturate solution.

a) KCl at 80C has y value of 51. so the solubility of KCl at 80C is 51g

b) In the similar way KClO3 has 46g

c) 80g

d) 10g

e) 60g
