1. Increasing the pressure
In order to increase the solubility of gases in a liquid solvent, we must increase the pressure of the gas. This is the reason that the carbonation of soft drinks is carried out under pressurized conditions.
2. Supersaturated
When a solvent is "saturated", it is holding as much solute as it can at the given conditions. When additional solute is added by changing the conditions, the solvent contains more solute than normal so it is "supersaturated".
3. The concentration by weight may be calculated by dividing the weight of the solute by the weight of the solution. This is:
Weight of solute = 20 g
Weight of solution = 20 + 59 = 79 g
Wt % = (20/79) * 100 = 25.32%
I think the question is incomplete as we need initial temperature to get the new temperature. but you can use equation Q=mc0 for guidelines
Q= energy
m= mass of solution
c= specific heat capacity of. solution
0= final temperature- initial temperature
Answer:
Haven't evaporated all of the water
Explanation:
One of the main sources of error that occur in a formula of a hydrate lab is that all of the water is not evaporated. We can see at the end of the video that half of the CoCl2 is a light blue colors and the other half is a dark blue color. This indicates that all of the water still has not been evaporated off, resulting in the actual mass of the salt to be greater than the predicted value.
