Answer:
5.5
Explanation:
Phenol is a weak acid that dissociates according to the following reaction.
C₆H₅OH(aq) ⇄ C₆H₅O⁻(aq) + H⁺(aq)
The pKa is 9.90. The acid dissociation constant (Ka) is:
pKa = -log Ka
Ka = antilog -pKa = antilog -9.90
Ka = 1.26 × 10⁻¹⁰
Given the concentration of the acid, Ca = 0.10 M, and the Ka, We can find [H⁺] using the following expression.
[H⁺] = √(Ka × Ca)
[H⁺] = √(1.26 × 10⁻¹⁰ × 0.10)
[H⁺] =3.5 × 10⁻⁶ M
The pH is:
pH = -log [H⁺]
pH = -log 3.5 × 10⁻⁶
pH = 5.5
Answer:
Methane + Bromine = (CH4+Br2)
Explanation:
When a mixture of methane and bromine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is bromomethane. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by bromine atoms. The reaction is a single-step reaction.
