Answer:
(a) Acid
(b) Base
(c) Acid
(d) Base
Explanation:
According to the Arrhenius acid-base theory:
- An acid is a substance that releases H⁺ in aqueous solution.
- A base is a substance that releases OH⁻ in aqueous solution.
(a) H₂SO₄ is an acid according to the following equation:
H₂SO₄(aq) ⇒ 2 H⁺(aq) + SO₄²⁻(aq)
(b) Sr(OH)₂ is a base according to the following equation:
Sr(OH)₂(aq) ⇄ Sr²⁺(aq) + 2 OH⁻(aq)
(c) HBr is an acid according to the following equation:
HBr(aq) ⇒ H⁺(aq) + Br⁻(aq)
(d) NaOH is a base according to the following equation:
NaOH(aq) ⇒ Na⁺(aq) + OH⁻(aq)
It is a moderate conductor of electricity, and in nature it is a dark indigo blue mineral. Density: 4.6g/cm^3. insoluble in water. melting point above 500 degrees C.
5
mL acetic acid
95
mL water
Explanation:
Since
5
%
of the vinegar, by volume, is acetic acid, and we have
100
mL of vinegar, we have
5
mL of vinegar.
Similarly, we have
100
%
−
5
%
=
95
%
being water, so we have
95
mL of water.
