Question

2. A student tested the solubility of five substances at different temperatures. He noted the amount of each substance dissolved in 100 g of water to form a saturated solution at a particular temperature and reported the following data: Substance dissolved Temperature 20°C 35°C 50°C А 18.6 21.4 23.8 B 20.0 25.0 35.0 C с 8.2 7.9 7.6 D 36.2 40.6 45.4 32.0 62.0 106.0 2(a) Which substance is least soluble and which substance is most soluble in water at 20°C ? 2(b) What is the concentration of solution B at 35°C ? 2(c) Find the amount of Ethat will separate out when 106.0 g of its solution at 50°C is cooled to 20°C. 200) Do all solutions show the same effect of temperature on the solubility of a salt?​
