An acid is defined as a proton donor this is because when dissolved in water it dissociates releasing a proton (h+) which combines with water molecules to form an acidic solution [h3o+] [oh–] on the other hand bases are defined as a substance present h3o+ hence reducing their concentration a base is thus defined.
For example, sodium hydroxide, adds na + and oh - to the water the reason that acids and bases cancel each other out is because the h + and oh - ions react to form water, leaving salts behind: hcl + naoh nacl (table salt) + h 20 this definition was fairly sound and research into these substances continued.
