Question

state differences between acids and bases​

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

Answer:

acids:

1)An acid is a molecule or substance that has a pH value less than 7.0 when it is present in an aqueous solution. An aqueous solution is any solution where water is a solvent. Acids are termed as compounds that donate H+ (hydrogen ion) to another compound known as base.

2)As per Arrhenius Concept, an acid elevates the concentration of Hydrogen ions when dissolved in water.

3)In the Bronsted-Lowry Concept, acids are substances which donate protons

4)Ions that accept the pair of electrons (electron pair acceptor – an electrophile), and possess vacant orbitals are termed ‘Lewis acid’.

5)Acids have a pH less than 7.0.

bases:

1)A base (alkaline) is a molecule or substance that has a pH value higher than 7.0 when present in an aqueous solution. Bases are the exact chemical opposite of acids. In chemistry. They are substances that, in aqueous solution, release hydroxide (OH−) ions.

2)As per Arrhenius Concept, a base is a compound that increases the concentration of hydroxide ions (OH–) when dissolved in water

3)Bases, on the other hand, are substances which accept protons

4)Ions that donate a pair of electrons (electron pair donor – a nucleophile), and possess a lone pair of electrons are termed ‘Lewis base’.

5)Bases have a pH higher than 7.0, and could even go up to 14 if the bases are very strong.
