If the base is a metal hydroxide, then the general formula for the reaction of an acid with a base is described as follows: Acid plus base yields water plus salt. For example, the reaction of equimolar amounts of HBr and NaOH to give water and a salt (NaBr) is a neutralization reaction:

Acid-base reactions are chemical reactions that involve the transfer of a proton (H + ). Examples include the reactions of acids with metals, carbonates, and Arrhenius bases, described in the following. Reactions of acids with metals. Metals tend to give out an electron and become cations.
To write the formula for a base, first write the symbol for the metal cation followed by the formula for the hydroxide ion. Then, balance the ionic charges just as you would for any ionic compound. For example, aluminum hydroxide consists of the aluminum cation (Al 3à) and the hydroxide anion (OH =).
Ironically, this is an oxidation/reduction ( REDOX) reaction, not an acid base reaction. M (s) + 2 HCl (aq) → MCl 2 (aq) + H 2 (g) Will react with aluminum to dissolve it, creating a solution of aluminum tetrahydroxide complex ions. 2Al (s) + 2NaOH (aq) + 6H 2 O ( l) → 2Na + + 2 [Al (OH) 4] – + 3H 2 (g).
The conjugate acid of the strong base is a weaker acid than water and has no effect on the acidity of the resulting solution. However, the conjugate base of the weak acid is a weak base and ionizes slightly in water. This increases the amount of hydroxide ion in the solution produced in the reaction and renders it slightly basic. A weak acid ...
And if you mix it in water again, you'll get some H plus ions. So this is also an acid. Similarly, let's take some example of bases. If you take sodium hydroxide or potassium hydroxide, mix them in water. Or take a solution, aqueous solution of them, you'll find sodium ions, potassium ions, and OH minus ions over here.
