Four grams (4 g) of NaNO, was dissolved in 10 mL of water and heated to 100°C. Upon cooling, the salt began to recrystallize at approximately 40C. Based on these observations, determine whether sodium or potassium nitrate used in your experiment is the more soluble salt. Explain your answer. pts) We were unable to transcribe this image8.
