Question

how much salicylic acid will dissolve in 10.0mL of water if the solvent is cooled in an ice bath?

How much boiling water would it take to dissolve 0.500g of salicylic acid?

Answer 1

Solubility of salicylic acid is water at 0 °C is 1.24 g/L

Solubility of salicylic acid is water at 100 °C is 77.79 g/L (boiling water)

Thus 1 gm of salicylic acid gets dissolved in 1000 mL of solution at ice bath (0 °C )

Then how much salicylic acid will get dissolve in 10 mL of water

Amount of salicylic acid dissolved = (10*1)/1000 = 0.01 gm = 10 mg of salicylic acid will be dissolved

At boiling water temperature (100 °C) 77.79 gm of salicylic acid is dissolved per litre of solution then

0.5 gm of salicylic acid will be dissolved in how much much of boiling water

Amount of boiling water required = (0.5*1000)/77.79 = 6.43 mL of boiling water
