Answer :
HCl : Bronsted-Lowry acid
: Lewis-acid
: Bronsted-Lowry base
: Lewis-base
Explanation :
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
HCl :
It is a Bronsted-Lowry acid that donates protons.
:
It is a Lewis-acid that accepts electron pairs.
:
It is a Bronsted-Lowry base that accepts protons.
:
It is a Lewis-base that donates electron pairs.
a.NH₃+HCl⇒NH₄Cl
b.volume HCl=150 ml
c. pH=4.82
<h3>Further explanation</h3>Reaction
NH₃+HCl⇒NH₄Cl
The equivalence point⇒mol NH₃=HCl
Titration formula :
M₁V₁n₁=M₂V₂n₂(n=acid base valence, NH₃=HCl=1)
mol NH₃
mol HCl=75 mlmol
- Volume HCl :
Volume total :
- molarity of salt(NH₄Cl)
mol NH₄Cl=mol NH₃=75 mlmol=0.075 mol
- pH of solution
