Similarly, NaF is basic (it is the salt of a strong base, NaOH, and a weak acid, HF). NaCl is neutral. This means that two of the solutions are basic (NH3 and NaF), one solution is neutral (NaCl), and the other is acidic (NH4Br).
Why is NaF a basic solution?
NaF is a basic salt having a pH value of more than 7, made from the neutralization of a strong base(NaOH) with a weak acid(HF). The aqueous solution of sodium fluoride(NaF) is basic in nature due to having more hydroxide ions produced from the hydrolysis of fluoride ions(F– + H2O → HF + OH–).
Will NaF produce a basic solution when dissolved in water?
Salts That Form Basic Solutions
When solid sodium fluoride is dissolved into water, it completely dissociates into sodium ions and fluoride ions. ... Salts that are derived from the neutralization of a weak acid (HF) by a strong base (NaOH) will always produce salt solutions that are basic.
