A saturated solution of barium chloride at 30 °C contains 150 g water. How much additional barium chloride can be dissolved by heating this solution to 80 °C? 2. A solution of KCl is saturated at 20 °C.

a) How many grams of solute are dissolved in 100 g of water?

b) What is the total mass of the solution?

c) What is the mass percent of this solution at 50 °C?

d) If the solution is heated to 50 °C, how much more KCl can be dissolved in the solution without adding more water?

e) If the solution is saturated at 100 °C and then cooled to 30 °C, how many grams of solute will precipitate out?

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
