Answer:
pH = 4.45
Explanation:
We need to find the pH of solution of HCl. We know that, pH of a solution is given by :
Put all the values,
So, the pH of the solution of HCl is 4.45.
Terrence measures the amount of water displaced by various objects when they are dropped into a graduated cylinder of water. By
looking at his data, he realizes that the amount of water displaced depends on either the mass or the volume of the object, depending on whether the object sinks or floats.

Answer:
The pH of the solution will be 7.53.
Explanation:
Dissociation constant of KClO=
Concentration of acid in 1 l= 0.30 M
Then in 200 ml =
The concentration of acid, HClO=[acid]= 0.006 M
Concentration of salt in 1 L = 0.20 M
Then in 300 ml =
The concentration of acid, KClO=[salt]= 0.006 M
The pH of the solution will be given by formula :
The pH of the solution will be 7.53.
The protons of methylene group between the two carbonyl groups in ethylacetoacetate are acidic in nature. When compounds containing such acidic protons are treated with bases the loose proton and form enolates.
In this particular example when ethylacetoacetate is reacted with methyl magnesium bromide, the methyl group abstracts the acidic proton and converts into methane gas. The enolate when hydrolyzed is again converted into ethylacetoacetate as shown below,
