Define Acid and Alkali.
ANSWER ⤵️
⛧ ACID ⛧

A liquid substance that can dissolve metal and may burn your skin or clothes. Acids have a pH value of less than 7.
SCIENTIFIC DEFINITION :
Acid, any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).
⛧ ALKALI ⛧
SIMPLE DEFINITION :
A chemical substance that reacts with acid to form a salt. An alkali has a pH value of more than 7.
SCIENTIFIC DEFINITION :
Alkali, any of the soluble hydroxides of the alkalimetals—i.e., lithium, sodium, potassium, rubidium, and cesium. Alkalies are strong bases that turn litmus paper from red to blue; they react with acids to yield neutral salts; and they are caustic and in concentrated form are corrosive to organic tissues.
