Q146928
Which of the following is true regarding acids?
a) Acids react with bases to form a solvated salt and water.
b) Acids do not react with water to form hydronium ions.
c) All listed answers are correct.
d) Acids react with solvated salts to form bases and water.
e) Acids react with other acids to form bases and salts.
Solution:
Let us check each statement.
a) Acids react with bases to form a solvated salt and water.
This is a true statement. Acids and bases react to form salt and water.
Example : NaOH (aq) + HCl (aq) ----> NaCl (aq) + H2O (aq)
............( Base)...... (Acid) ........... (salt) ..... (water).
b) Acids do not react with water to form hydronium ions.
This is a false statement.
Acids and water do form a hydronium ion.
Example : HCl (aq) + H2O(l) -----> Cl – (aq) + H3O + (aq)
..............( Acid)........(water)........(anion).....(hydronium ion)
c) All listed answers are correct.
This is also a false statement because we can see that ‘a’ is true and ‘b’ is false.
So not all listed in the given question are correct.
d) Acids react with solvated salts to form bases and water.
This is a false statement. Acids can just undergo a substitution reaction with the salt.
HCl (aq) + KF (aq) ----> HF (aq) + KCl (aq)
(Acid).......( salt) ..........(hydrofluoric acid) (salt)
e) Acids react with other acids to form bases and salts.
This is a false statement. If we mix two acids of comparable strength. Then they won’t react with each other. They will both give out H+ (H3O+ ) and corresponding anion.
HCl (aq) + HBr (aq) + 2H2O(aq) -----> 2 H3O+ (aq) + Cl - (aq) + Br - (aq)
