4.2.3 Soluble salts

• Soluble salts are ionic compounds that dissolve in water to form ions
• An example of an insoluble salt is silver chloride.
• Increasing the temperature usually increases the solubility of many salts.

  True
• What is the chemical formula for sodium chloride?

  $\text{NaCl}$
• What type of ions do salts with small, highly charged ions or large, weakly charged ions have?

  Highly charged ions
• Which base reacts with hydrochloric acid to form sodium chloride?

  Sodium hydroxide
• Acids react with bases to form soluble salts, such as hydrochloric acid (HCl) reacting with sodium hydroxide (NaOH) to produce sodium chloride
• What type of ions tend to make salts more soluble?

  Small, highly charged
• Steps in the dissolution process of a soluble salt:

  1️⃣ Water molecules surround ions

  2️⃣ Ionic lattice breaks apart

  3️⃣ Ions are hydrated
• In neutralization, an acid reacts with a base to form a salt and water
• Match the soluble salt with its use:

  Sodium chloride ↔️ Food preservation

  Potassium nitrate ↔️ Fertilizers

  Copper sulfate ↔️ Fungicide
• Solubility refers to the amount of a salt that can dissolve in a certain volume of water at a given temperature.


  True
• What happens to the ionic lattice during the dissolution process of soluble salts?

  Water molecules break it
• How are soluble salts formed?

  By reacting acids with bases
• The solubility of a salt depends on the nature of the ions that make up the salt.

  True
• During dissolution, water molecules break apart the ionic lattice.
• What happens to the ionic lattice during dissolution?

  Breaks apart
• What does solubility refer to?

  Amount of salt dissolved
• Soluble salts are formed when an acid reacts with a base.


  True
• Hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to form the soluble salt sodium chloride
• What soluble salt is formed when hydrochloric acid reacts with sodium hydroxide?

  Sodium chloride
• What precipitate is formed when barium chloride reacts with sodium sulfate?

  Barium sulfate
• What industrial chemicals can sodium chloride be used to produce?

  Chlorine, sodium hydroxide
• What are soluble salts?

  Ionic compounds that dissolve
• What is an example of a soluble salt?

  Potassium nitrate
• Steps involved in the dissolution process of a soluble salt

  1️⃣ Water molecules surround ions

  2️⃣ Ionic lattice breaks apart

  3️⃣ Ions are hydrated
• An example of a soluble salt is potassium nitrate.
• Which acid reacts with sodium hydroxide to form sodium chloride?

  Hydrochloric acid
• Increasing temperature generally increases the solubility of salts.

  True
• During dissolution, water molecules surround the ions and break apart the ionic lattice
• Match the soluble salt with its insoluble counterpart:

  Potassium nitrate ↔️ Silver chloride

  Sodium chloride ↔️ Lead(II) sulfate
• Solubility is the amount of salt that can dissolve in a certain volume of water at a given temperature.

  True
• Neutralization is one method for preparing soluble salts.

  True
• Evaporation is used to obtain the resulting soluble salt after preparation.
