For the first question regarding the solution of 10 grams KCl at 10 degrees Celsius, it is important to consider the solubility of KCl at that temperature. KCl is quite soluble in water, and at 10 degrees Celsius, the solubility is around 30.6 grams per 100 grams of water (this value can vary slightly based on sources). Since 10 grams is well below this limit, the solution is:
**a. unsaturated**
For the second question about increasing the rate at which the salt dissolves, the options provided include:
a) cooling the water
b) using salt cubes instead of crushed salt
c) stirring the solution
The option that would increase the rate at which the salt dissolves is:
**c. stirring the solution**
Stirring increases the interaction between the salt and the water, allowing the salt to dissolve more quickly.
**a. unsaturated**
For the second question about increasing the rate at which the salt dissolves, the options provided include:
a) cooling the water
b) using salt cubes instead of crushed salt
c) stirring the solution
The option that would increase the rate at which the salt dissolves is:
**c. stirring the solution**
Stirring increases the interaction between the salt and the water, allowing the salt to dissolve more quickly.
