Part A Predict whether a solution of each of the following salts is acidic, basic, or pH neutral. Drag the appropriate items to their respective bins. Reset Help acidic basic pH neutral ΝΗ,NO, КСІ Ca(OC), NaNO3 Submit Previous Answers Request Answer

Answer 1

a) NH4NO2

It is a salt of weak base and weak acid. So, its nature depends on Ka and Kb values.

Ka of HNO2 = 4.5 x10^-4

Kb of NH4OH = 1.8 x10^-5

Ka is greater than Kb .

So, this is acidic in nature. PH <7

b) Ca(OCl)2

It is a salt of strong base Ca(OH)2 and weak acid HOCl.

So, it is basic in nature. PH >7

c) KF

It is a salt of strong base KOH and weak acid HF.

So, it is basic in nature. PH>7

d) KCl

It is a salt of strong base KOH and strong acid HCl

So, it is neutral in nature . PH=7

e) NaNO3

It is a salt of strong base NaOH and strong acid HNO3.

S0, it is neutral in nature. PH=7

acidic ---------------- NH4NO2

basic --------------   Ca(OCl)2 , KF

neutral --------------   KCl and NaNO3.
