Answer: The pH of phenol solution is 4.7
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
Given : ![[H_3O^+]=1.8\times 10^{-5}M](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D1.8%5Ctimes%2010%5E%7B-5%7DM)
Putting in the values we get
![pH=-\log[1.8\times 10^{-5}M]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B1.8%5Ctimes%2010%5E%7B-5%7DM%5D)
Thus pH of phenol solution is 4.7

Answer :
In my opinion , answer is A
Answer:
( a ) soluble
( b ) soluble
( c ) insoluble
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. ,<u> if a compound is polar then it will dissolve in a polar compound only , </u>and
<u>if a compound is non - polar then it will dissolve in a non - polar compound only .</u>
Hence , from the question ,
( a )
Methanol and water as we know are both polar species , hence , according to the principle - soluble .
( b )
Hexane and cyclohexane
Both the species are polar species , hence , according to the principle - soluble .
( c )
Hexane and water
In this case ,
Hexane , is non polar and water is polar , hence , the mixture will be non soluble .
I'm assuming that it is due to the breeze coming from the tides.
