Explanation:
The solubility curve helps us to compare the solubility of difference substances at same temperature. It gives the idea that solubility changes with the temperature. The solubility curve helps us to predict which substance will crystalize out first from hot solution containing two or more solutes.
Answer:
The larger piston
Explanation:
(i just took the same test)
Answer:
12.1; acidic
Explanation:
I'm assuming the hydrogen concentration is H+.
So, first we must find pH.
pH = -log[H+]
I simply just plugged in the concentration.
I get 1.9 as the pH. This means that the substance is very acidic since it has a low pH.
Now to find poH.
poH + pH = 14
I simply plugged in once again!
I get 12.1 as the poH. This also determines that the substance is very acidic since it has a high poH.
