Question

• Take approximately 50 mL of water each in two separate beakers.
• Add salt in one beaker and sugar or barium chloride in the second beaker with continuous stirring.
• When no more solute can be dissolved, heat the contents of the beaker to raise the temperature by about 5°C.
• Start adding the solute again.

Is the amount of salt and sugar or barium chloride, that can be dissolved in water at a given temperature, the same?

Answer 1

At a constant temprature the amount of solute tht can be added is same...for example...only 40g of salt can be dissolved in 100 mL of water at 25°C.But by increasing the temprature more amount of solute can be dissolved.

MORE SOLUTE CAN BE DISSOLVED IF
1.Temperature of the solution is increased
2.amount of sovlent is increased.

Hope the answer helped ....comment below if doubt persists...!!!  :)

Answer 2

Answer:

No they will differ as salt is more soluble than sugar,,so at the same temperature the level of solubility differ.
