Question

write the name and formula of two of each: strong acid
weak acid
strong base
weak base
indicator
neutral salt
acidic salt
basic salt

Answer 1

Strong acid = HCl - hydrochloric acid

HNO3 - nitric acid

H2SO4 - sulfuric acid (HSO4- is a weak acid)

HBr - hydrobromic acid

HI - hydroiodic acid

HClO4 - perchloric acid

HClO3 - chloric acid

Week acid = HO2C2O2H - oxalic acid

H2SO3 - sulfurous acid

HSO4 - - hydrogen sulfate ion

H3PO4 - phosphoric acid

HNO2 - nitrous acid

HF - hydrofluoric acid

HCO2H - methanoic acid

C6H5COOH - benzoic acid

CH3COOH - acetic acid

HCOOH - formic acid

Strong base = NaOH - sodium hydroxide

KOH - potassium hydroxide

RbOH - rubidium hydroxide

CsOH - cesium hydroxide

*Ca(OH)2 - calcium hydroxide

Week base = Acetic.

Trichloroacetic.

Hydrofluoric. Hydrocyanic

Answer 2

strong acid : (1) hydrochloric acid   (HCl)        :   (2) sulfuric acid   (H2SO4)

weak acid : (1) formic acid   (HCOOH)   :  (2) hydrocyanic acid  (HCN)

strong base : (1) Potassium hydroxide (KOH)     :  (2)  Sodium hydroxide (NaOH)

weak base:  (1)  ammonia (NH3)         :  (2) Methylamine  (CH3NH2)

indicator : (1) litmus      :  (2)  red Cabbage juice

neutral salt  :(1)  Sodium chloride (NaCl)  :  (2)  Potassiumdichromate (K2Cr2O7)

acidic salt : (1) sodium bicarbonate (NaHCO3) : (2) sodium bisulfate (NaHSO4)

basic salt :(1) Sodium chloride (NaCl) : (2) Potassium dichromate (K2Cr2O7)
