Solubility of which among the following solids in water changes slightly with temperature?
(A) KNO3 (B) NaNO3 (C) KBr (D) NaBr

Dear student,

Solubility usually increases with temperature, however this depends on whether the reaction is exothermic or endothermic.

NaBr having a sufficiently high lattice energy do not change its solubility much on increasing the temperature as evident from the graph.

Hope this helps,
