this is the concentration required to initiate precipitation
Explanation:

Precipitation starts when ionic product is greater than solubility product.
Ip>Ksp
Precipitation starts only when solution is supersaturated because solution become supersaturated then it does not stay in this form and precipitation starts itself only solution become saturated.
This usually happens when two solutions containing separate sources of cation and anion are mixed together and here also we are mixing lead (||)nitrate solution(source of lead(||)) into the Cl- solution.
lets solubility=S
this is the concentration required to initiate precipitation
<u>Answer:</u>
211.9 J
<u>Explanation:</u>
The molecules of water release heat during the transition of water vapor to liquid water, but the temperature of the water does not change with it.
The amount of heat released can be represented by the formula:
where = heat energy,
= mass of water and
= latent heat of evaporation.
The latent heat of evaporation for water is and the mass of the water is
.
The amount of heat released in this process is:
211.9 J
