For the pH of a solution prepared by dissolving 0. 350 mol of solid methylamine hydrochloride, the pH is mathematically given as
pH = 11.14
<h3>What is the pH value of a solution prepared by dissolving 0. 350 mol ?</h3>
Generally, the equation for the pKb is mathematically given as
pKb = -logKb
Therefore
pKb of CH3NH2 = -log(4.40×10-4)
pKb of CH3NH2= 3.36
Hence
pKa= 14 - pKb
pKa= 14 - 3.36
pKa= 10.64
In conclusion, using
pH = pKa + log([A-]/[HA])
pH = 10.64 + log(1.10M/0.350M)
pH = 11.14

Desalination is a process that takes away mineral components from saline water.
<span>No, I believe this is not an example of a chemical reaction.
What we actually see here is a physical change of the solution. Since we are adding
more water to an aqueous solution which is also made up mostly of water, what
we are simply basically doing is dilution. Since the solution is being diluted,
so definitely the color turned lighter.</span>
It is basic because of the fact that it has a strong base which is KOH and a weak acid HCN and the strong base causes it to remain more basic.
