Explanation:

1. N/A

2. The difference in color

3. It is making the solution less concentrated, usually by adding more liquid.

4. You need to find the concentration of the solution before it was diluted. Add more of the solvent to the solute as per needed.

a 1 molar solution cannot be made by adding one mole of solute to 1 L of solvent. • Solutions of a desired molality are usually prepared by placing the appropriate amount of solute

Calculate the molar solubility of lead thiocyanate in pure water. The molar solubility is the maximum amount of lead thiocyanate

OLga [1]

Answer:

$Molar solubility(S)=1.71\times10^{-2} mole/litre$

Explanation:

Assume Ksp of $Pb(SCN)_{2}$ = $2\times10^{-5}$ ( it is general value ,i took it because not given in question)

molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.

Ksp=solubility product;

$Pb(SCN)_2= Pb^{2+} +2SCN^-$

Lets molar solubilty of $Pb(SCN)_2$ is S then

$[Pb^{+2}]=S;$

$[SCN^{-1} ]=2S;$

$Ksp =S\times(2S)^{2} =2\times10^{-5}$

$4S^{3}=2\times10^{-5}$

$S=1.71\times10^{-2} mole/litre$
