Question

What is the difference between an acid and a base?

Answer 1



A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.

Answer 2

`{\underline{\underline{\bf{\red{\:\:Acid\:\:}}}}}`

• Proton donor and electron pair acceptor
• It can increase the concentration of H+ ion in aq. solution.
• pH value is <7
• Turn blue litmus paper into red
• Acid reacts with bases to form salts
• Acid taste sour
