Explain the differences between acid and base
Answers
Answer:
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.
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.
The main difference is that Acids are proton donors or electron pair acceptors whereas Base are proton acceptors or electron pair donors.
Acids are sour in taste while Bases are bitter in taste.
Acids are corrosive in nature whereas Bases are soapy in nature.
Acids turn blue litmus paper into red whereas in case of Bases they turn red litmus paper into blue.
Acids have pH less than 7 but Bases have pH greater than 7.
Acids react with metals to produce compound and hydrogen gas while bases do not react with metals .
Acids are able to increase the H+ ions concentration in an aqueous solution whereas Bases are able to increase the OH- ions in an aqueous solution.
