Asolution contains 50g of kcl per 100g of water at 100 degrees celsius. is solution saturated, unsaturated or supersaturated

The solution is Unsaturated

Explanation:

Nature of solution (saturated , unsaturated or supersaturated) depends on solubility of that salt in water. Because solubility of KCl in water is about 360.5g / 100g of water at 100 degree celcius. So, some amount of KCl will remain undissolved in water.Hence, it is an unsaturated solution.

We are given 50g of KCl per 100g water at 100 degrees celcius,

now mass of KCl = mass of K + mass of Cl = 39+35.5 = 74.5g

So, Molar mass of KCl = = 0.6711 moles

And Molar mass of 100g water =   = 5.55moles

Now, to find property of solution we divide the molar masses,  

  = 12.07% this is the quantity of solute in water which makes the solution an unsaturated solution.
