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

• 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

• Proton acceptor and electron pair donor
