Neutralization Reactions

These flashcards cover key vocabulary and concepts related to neutralization reactions.

Neutralization Reaction

• A double displacement reaction

• occurs when acids and bases are mixed

• neutralizes both substances

• Forms water and a salt

The hydroxide ion (OH-) and hydrogen (H+) ions

react to form

Water

The metal cation and non-metal anion combine to form a

Salt

The goal of neutralization reaction

to from products with a pH closer to 7 (neutral)

Predicting the Products of Neutralization Reactions

If we know the reactants of a neutralization

reaction, we can predict the products by using the

double displacement model.

Chemical Spills and Neutralization Reactions

• Sulfuric acid (H2SO4) and sodium hydroxide

(NaOH)

• calcium oxide/ lime Ca0(s) was added

1.CaO(s) + H2O(l) → Ca(OH)2 (aq)

2. Ca(OH)2 (aq) + H2SO4 (aq) → 2H 2O(l) + CaSO4 (aq)

Antacids

• Acidic stomach acid can irritate the stomach lining

• Antacids contain hydroxide and carbonate neutralize stomach acid

• Milk of magnesia Mg(OH)2 is not very soluble in water so it produces a low concentration of hydroxide atoms, so it doesn’t cause chemical burns but provides relief

What’s the PH of stomach

1.5

Neutral pH

A pH level of 7, indicating a neutral solution.

Double Displacement Model

A method used to predict the products of reactions between two ionic compounds.

Calcium Oxide (CaO)

A chemical compound used in the neutralization of sulfuric acid during chemical spills.

Milk of Magnesia

A common antacid that contains magnesium hydroxide (Mg(OH)2) and is used to neutralize stomach acid.

Products of Neutralization

Water and salt formed as a result of an acid-base neutralization reaction.

Example of a Neutralization Reaction

HCl(aq) + NaOH(aq) → HOH(aq) + NaCl(aq)
