Is HCl (Hydrochloric acid) an Acid or Base?
Answer:
HCl (Hydrochloric acid) is an acid.
Explanation:
Today we will know about whether HCl (hydrochloric acid) is an acid or Base in just four steps.
Step-1:
HCl gives hydrogen ion into water ,H₂O.We know that an acid gives hydrogen ion in water.So HCl is an acid.HCl is an acid according to Arrhenius concept of acid and base concept.
HCl ----> Cl + H+
Step-2:
HCl reacts with an base to produce salt and water.So HCl is an acid.
HCl +NaOH ----> NaCl + H₂O
HCl =Acid
NaOH =Base
NaCl=Salt
H₂O =Water
Step-3:
HCl gives proton(H+) to a base NH₃.Since HCl is a proton donar , HCl is an acid.According to Brønsted–Lowry concept of acid and base, also called proton theory of acids and bases, HCl is an acid.
HCl +NH₃ ----> NH₄Cl
Step-4:
HCl turns blue litmus paper into red.We know that an acid can do that.So,HCl is an acid.
