The weak acid will have fewer ions than the strong acid of similar concentration.
The chemical reactions for a weak acid and a strong acid is given below:
- Strong acid: HA → H⁺ + A⁻
- Weak acid: HA ⇆ H⁺ + A⁻
<h3>What are strong and weak acids?</h3>
Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.
Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.
Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.
The equation of the dissociation of strong acids and weak acids are given below:
- Strong acid: HA → H⁺ + A⁻
- Weak acid: HA ⇆ H⁺ + A⁻
In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.

Answer:
240 g/mol
Explanation:
We'll begin by writing the chemical formula of Disodium sulfide nonahydrate. This is illustrated below:
The molecular formula of disodium sulfide nonahydrate is Na₂S.9H₂O
Finally, we shall determine the molar mass of disodium sulfide nonahydrate, Na₂S.9H₂O. This can be obtained by adding the individual molar mass of the element present in the compound as illustrated below:
Molar mass of Na₂S.9H₂O = (23×2) + 32 + 9[(2×1) + 16]
= 46 + 32 + 9[2 + 16]
= 46 + 32 + 9[18]
= 46 + 32 + 162
= 240 g/mol
Thus, the molar mass of disodium sulfide nonahydrate, Na₂S.9H₂O is 240 g/mol
Answer: Aluminum is the metal that does not corrode in the air.
Explanation:
Corosion is a natural process in which pure metals converted into oxides and reduce the life of metals.
Aluminum atom is a metal that belongs to react with the oxygen present in the air making aluminum oxides. These oxides attaches to the surface and does not allow another oxygen molecule entering it which prevent the process of corrosion.
