Solubility is the property of the solute to dissolve itself in a solvent. The states of the solute and solvent may range from solid, liquid, and gas. Since the statement above states a solution instead of a solvent. The answer is false. solution is composed both of the dissoved solute and solvent.
When a cold air mass meets a warm air mass, a front is formed; if the cold air is replacing the warm air, it is known as a cold front. Cold fronts frequently cause rain showers or thunderstorms because they force air in a steep upward direction at the front's edge. They also bring about changes in wind direction and atmospheric pressure.

Explanation:
We have to calculate value.
It is known that at the equivalence point concentration of acid is equal to the concentration of anion formed.
Hence, [HA] =
Now, relation between and pH is as follows.
pH =
Putting the values into the above formula as follows.
pH =
4.23 = (as [HA] = )
= 4.23 (as log (1) = 0)
or, = 4
Thus, we can conclude that of given weak acid is 4.
