H
Since K stands for potassium, C stands for Carbon and O stands for Oxygen
Answer:
It is Soluble
Explanation:
Name- Magnesium acetate
It dissolves easily in water and alcohol.
Answer:
These substances are called amphiprotic. Water, amino acids, hydrogen carbonate ions, and hydrogen sulfate ions are common examples.
Explanation:
A substance is amphoteric (from Greek amphoteros = "each of two") if it can act as an acid or a base.
For example, aluminum hydroxide is amphoteric because it can act as a base and neutralize strong acids.
Answer:
Few important points related to
reaction:
1.
is a one-step reaction that follows second order kinetics.
2. In
reaction, a transition state is formed in situ.
3. Strong nucleophiles like
are used in case of bi-molecular nucleophilic substitution reaction.
Ethyl acetate can be prepared by a second-order nucleophilic substitution reaction between acetic acid and ethyl bromide.
The reaction between acetic acid and ethyl bromide is drawn below:
Kw = 1.219x10⁻¹⁴
kw = [H⁺] x [OH⁻]
in water [H⁺] = [OH⁻] therefore:
[H⁺] = √ kw
[H⁺] = √ <span>1.219x10⁻¹⁴
[H</span>⁺] = 1.104x10⁻⁷
pH = - log [H⁺]
pH = - log [ <span>1.104x10⁻⁷ ]
pH = 6.95
