`color{green}("πππππππππππ :")` Hydrogen ions in `color{red}(HCl)` are produced in the presence of water. The separation of `color{red}(H^+)` ion from `color{red}(HCl)` molecules cannot occur in the absence of water.
`color{red}(HCl + H_2O β H_3 O^(+) + Cl^(-))`
Hydrogen ions cannot exist alone, but they exist after combining with water molecules. Thus hydrogen ions must always be shown as `color{red}(H^(+) (aq))` or hydronium ion `color{red}((H_3O^+ ))`.
`color{red}(H^(+) + H_2O β H_3 O^(+))`

Bases generate hydroxide `color{red}((OH^β ))` ions in water. Bases which are soluble in water are called alkalis.

All bases do not dissolve in water. An alkali is a base that dissolves in water . They are soapy to touch , bitter and corrosive . Never taste or touch them as they may cause harm. Which of the bases in the table 2.1 are alkalis ?
So from above discussion we inferred that all acids generate `color{red}(H^+)` ions (aq) and all bases generate `color{red}(OH^- (aq))`. So neutralization reaction can also be observed as:
