Identifying acidic, basic, and neutral salts and ions exam 3

Add H+ (arrhenius)

to anions and OH- to cations

Add H+ (bronsted)

to anions and remove H+ from cations

Salt hydrolysis occurs

when ions produced by the dissociation of a salt react with water to produce either hydroxide ions or hydronium ions. Think of two steps the dissociation of the salt and the equilibrium reaction with water for acidic or basic salts

what are the two steps of salt hydrolysis

the dissociation of the salt and the equilibrium reaction with water for acidic or basic salts

Basic salts

contain conjugate bases of weak acids

Acidic salts

contain conjugate acids of weak bases

salts are

ionic compounds when dissociated in water, the ion can act as an acid or base or be pH neutral

Strong acids

HCl

HNO3

HClO4

Strong bases

NaOH KOH

Weak Acid

CH3COOH

HF

HNO2

Weak Base

NH3

CH3NH2

Strong acids is paired with this conjugate

ph neutral conjugate anion

strong base is paired with this conjugate

pH neutral conjugate cation

weak acid is paired with this conjugate is

basic conjugate weak anion

weak base is paired with this conjugate

acidic conjugate weak cation

A cation that will amen a solution acidic is

the conjugate acid of a weak base

a small highly charged metal ion other than group 1A or 2A

A anion that will make a solution basic is

conjugate base of a weak acid

a cation that will not affect the pH of a solution is

group 1A or heavy group 2A except Be2+

an anion that will not affect the pH of a solution is

the conjugate base of a strong acid

if the salt cation is the countering of a _____ and the anion is the ____ of a ____ it will form a Neutral solution

if the salt cation is the countering of a strong base and the anion is the conjugate base of a strong acid it will form a neutral solution

if the salt cation is the countering of a _____ and the anion is the ____ of a ___ it will form a Basic solution

if the salt cation is the countering ion of a strong base and the anion is the conjugate base of a weak acid it will form a basic solution

If the salt cation is the conjugate acid of a weak base and the anion is the conjugate base of a strong acid it will form a _______

acidic solution

if the salt cation is a highly charged metal ion and the anion is the conjugate base of a strong acid, it will form an ______

acidic solution

if the salt cation is the conjugate acid of a weak base and the anion is the conjugate base of a weak acid, the pH of the solution depends on the

relative strengths of the acid and base
