The common ion effect for ionic solids (salts) is to decrease the solubility of the ionic compound in water significantly. explain the common ion effect in detail.

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-

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.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

will have a gram-molecular weight of 352g.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
