The pH of a solution prepared by dissolving 0. 350 mol of solid methylamine hydrochloride (CH3NH3Cl) in 1. 00 L of 1. 10 M methy
MrMuchimi

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

A student makes observations when water is added to a blue solution of copper sulfate. The student makes only 1 observation: the
horrorfan [7]

<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>

Hydrocyanic acid is a weak acid. Therefore, the salt KCN is
Step2247 [10]
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.
