Question

Shraddha tested the solubility of five substances at different temperatures. She noted

the amount of each substance dissolved in l00 g of water to form a saturated solution

at a particular temperature and reported the following data: (attached)

i) Which substance is least soluble in water at 20°C?


(ii) Which substance is most soluble in water at 20°C?


(iii) What mass of B would be needed to make a saturated solution in 50 g of water at

20°C?


(iv) Find the amount of E that will separate out when 106.0 g of its solution at 50°C is
cooled


(v) Do all solutions show the same effect of temperature on the solubility of salt?

If you answer fully i will mark you as brainliest today itself! ​

Answer 1

Answer:

shraddha tested the solubility of three different substances at different temperatures and collected the data as a given above (results are given in the following table, as grams of the substance dissolved in 100 grams of water to form a saturated solution).

Which salt has the highest solubility at 393 K?
