Chemical Reactions - Neutralization

____ are a type of double-displacement reaction that occurs when an acid and base chemically react to form salt and water.

• Decomposition reactions
• Neutralization reactions
• Synthesis reactions
• Combustion reactions

​ (a)   reactions occur when a part of two​ (b)   compounds is exchanged and makes two new components

• Double displacement
• ionic

​A displacement reaction is the one wherein the ​ (a)   or a set of atoms is displaced by another atom in a ​ (b)   . For instance, when iron is added to a copper sulphate solution, it displaces the copper metal.

• molecule

Neutralization reactions are a type of (a)   reaction that occurs when an (b)   and base chemically react to form (c)   and water. The hydrogen ion from the acid combines with the hydroxide ion from the ​ (d)   , forming water. The salt that is formed is dependent on the ​ (e)   . acid + base → salt + water

• salt
• base
• acid and base

an ion is

• An ion is a charged atom or molecule.
• An ion is a solid substance.
• An ion is a type of chemical bond.
• An ion is a neutral atom.

Ions will have either a negative charge or positive charge bc they will have an uneven number of protons and electrons.

• cations are positive

  more protons than electrons

• anions are negative

  more electrons than protons

What base and acid form water?

• An acid and a gas form water.
• An acid and a base form water.
• A base and a salt form water.
• A base and a liquid form water.

What base and acid form water?

• hydrogen ion from an acid and a hydroxide ion base form water.

• hydroxide ion from an acid and a hydroxide ion hydrogen ion base form water.

In the following ​ (a)   between a strong ​ (b)   (HBr) and strong base (KOH), water and a salt (KBr) are formed.

HBr acid  +KOH base→ KBr   +H2Owater

• acid
• reaction

When a strong acid reacts with a strong base in equal quantities, the resulting solution will be ​ (a)   (pH = 7) because there are equal amounts of the hydrogen ion (H+) and the ​ (b)   (OH-).

• neutral
• hydroxide ion
