Acids and Bases - Britney

An acid dissociates in water to form....

Answer explanation

An acid dissociates in water to form H+ ions. HCl while an Arrhenius base dissociates to produce OH- ions in water e.g. NaOH

Examples of Acids are

• HCl

• NaCl

• CH3COOH

• C2H5OH

What are examples of a Base

• CH4

• NH4OH

• Ca(OH)2

• C12H22O11

According to Brønsted and Lowry define an acid

According to Brønsted and Lowry what is a base?

In the chemical formula

HCl (aq) + NaOH (aq) → NaCl (aq)+ H2O (l)

identify the Arrhenius acid

• HCl (aq)

• HCl (g)

• NaOH (aq)

• NaCl (aq)

• H2O (l)

 

In the chemical formula

2KOH (aq) + H2SO4 (aq) → K2SO4 (aq)+ 2H2O (l)

identify the Arrhenius base.

• NaOH (aq)

• H2SO4 (aq)

• 2KOH (aq)

• K2SO4 (aq)

• 2H2O (l)

identify the Brønsted-Lowry acid(s) and base(s).

HCO2H (aq) + H2O (l) ⇌ HCO2 - (aq) + H3O+ (aq)

• Acid - HCO2H (aq)

  Base - H2O (l)

• Acid - HCO2 - (aq)

  Base - H3O+ (aq)

• Acid - HCO2H (aq)

  Base - H3O+ (aq)

• Acid - H2O (l)

  Base - HCO2 - (aq)

identify the Brønsted-Lowry acid(s) and base(s).

CH3CH2NH2 (aq) + H2O (l) ⇌ CH3CH2NH3 + (aq) + OH- (aq)

• Acid - OH- (aq)

  Base - CH3CH2NH2 (aq)

• Acid - + H2O (l)

  Base - CH3CH2NH3 + (aq)

• Acid - H2O (l)

  Base - CH3CH2NH2 (aq)

• Acid - CH3CH2NH3 + (aq)

  Base - H2O (l)

Identify the conjugate acid-base pairs.

CH₃CH₂OH + H₂SO₄ ⇌ HSO₄ ^- + CH₃CH₂OH₂ ⁺

• CH3CH2OH/ CH3CH2OH2 +

• H2 SO4/ CH3CH2OH2 +

• H2 SO4 / HSO4 -

• CH3CH2OH/ HSO4 -
