#### Explanation:

According to Arrhenius an acid is a substance that in water can give ${H}^{+}$ions. You can have strong or weak acids.
Strong acids are for example: HCl, HI, HBr and all the acids that in their formula have two oxygen atoms more than Hydrogen ones like ${H}_{2} S {O}_{4} , H N {O}_{3} , H C l {O}_{4}$...
Weak acids have less than 2 in this difference like ${H}_{2} C {O}_{3} , {H}_{3} B {O}_{3} , H I O$...

There are also organic acids with the group -COOH like acetic acid $C {H}_{3} C O O H$

According to Broensted-Lowry acid is also that substance that can give ${H}^{+}$ions to other substances
for example $N {H}_{4}^{+} + {H}_{2} O = N {H}_{3} + {H}_{3} {O}^{+}$

According with Lewis acid are also that substance that have an electronic vacation as $A l C {l}_{3}$ that in HCl gives
$A l C {l}_{3} + H C l = A l C {l}_{4}^{-} + {H}^{+}$
