Question

how do you identify acid and a base​

Answer 1

Answer:

identify acid and a base

To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions).

Answer 2

Answer:

to determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions). These definitions are normally applied to the reactants on the left.

If the reaction is viewed in reverse a new acid and base can be identified. The substances on the right side of the equation are called conjugate acid and conjugate base compared to those on the left.

Also note that the original acid turns in the conjugate base after the reaction is over.

Explanation:

Step 1: Identify the substance as an Arrhenius acid or base using the following criteria.

The names of the acids end in “acid”. Acid formulas have one of these forms: HX(aq) or HaXbOc.

Ionic compounds that contain hydroxide

(OH-) , carbonate (CO32-) , or hydrogen carbonate (HCO3-) anions are basic. Ammonia, NH3, is also a base.

Step 2: If the substance is an acid or base, determine whether it is strong or weak.

All common acids except HCl(aq), HNO3, and H2SO4 are weak.

All common bases except metal hydroxides are weak.
