Answer:
Explanation has been given below.
Explanation:
Let's consider solubility equilibrium of an ionic insoluble compound e.g. 
Equilibrium constant of this solubility equilibrium is represented in terms of solubility product (
) which is expressed as-
![K_{sp}=[Ba^{2+}][SO_{4}^{2-}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BBa%5E%7B2%2B%7D%5D%5BSO_%7B4%7D%5E%7B2-%7D%5D)
Now, if we add an ionic salt e.g. 
with a common ion 
then concentration of increases.
But, at a constant temperature, is constant.
Therefore, to keep constant, excess amount of will combine with free 
ion in solution and produce .
Hence, as a whole, solubility of decreases.
Answer:
no
Explanation:
pure water does not conduct electricity. Any impurities, like salts, in the water enable it to conduct electricity.
True
Carbon monoxide is a primary pollutant which no odor results from incomplete combustion of fuel. The man sources are gasoline and burning of biomass.
Depending on the source of emission, pollutants can be classified into two groups that is primary and secondary pollutants.
A primary pollutant is emitted in the atmosphere directly from a source. It can be either natural sch as volcanic eruptions, sandstorms or man-made that is due to industrial and vehicle emissions. Examples of primary pollutants are nitrogen oxides, carbon monoxide and particulate matter.
Secondary pollutant is due to interactions between primary and secondary pollutants. These can be chemical or physical interactions. Examples are photo-chemical oxidants and secondary particulate matter.
Therefore, carbon monoxide CO is a primary pollutant.
An alum is a double salt where you have a trivalent metal sulfate and a monovalent metal sulfate. Meanwhile, a crystal of potassium aluminum sulfate is potash alum!
