The solubility of KClO3 in 25 oC is 10 g solute per 100 g water
if 15 g of KClO3 is embedded in 100 g water in 25 oC , then , what is the amount of KClO3 that can be dissolved ?
is the solution unsaturated , saturated , or super saturated ?
thank you
What do you mean by embedded. Do you mean you dissolved 15g or you added 15g KClO3.
Yes , added
Did I miss something here? If the solubility of KClO3 is 10g/100g H2O and you add 15 g KClO3 to 100 g H2O, then it will dissolve 10 g KClO3 and the other 5g KClO3 will be unaffected. Of course the solution is saturated after the water has dissolved all it can.
To determine the maximum amount of KClO3 that can be dissolved in 100 g of water at 25°C, we compare it to the solubility of KClO3 at this temperature, which is given as 10 g solute per 100 g water.
The mass of KClO3 that can be dissolved can be calculated using the following formula:
Maximum amount of KClO3 = Solubility x Mass of Water
Plugging in the values, we have:
Maximum amount of KClO3 = 10 g/100 g x 100 g = 10 g
Therefore, the maximum amount of KClO3 that can be dissolved in 100 g of water at 25°C is 10 g.
Since you have 15 g of KClO3 in 100 g of water, which is greater than the maximum solubility of 10 g, the solution is considered supersaturated.
