Define a salt. Give three examples of salts with their chemical formulae.

Here are the answers to your chemistry assignment, Balogun: 1. Define a salt. Give three examples of salts with their chemical formulae. A salt is an ionic compound formed when the hydrogen ion of an acid is replaced by a metal ion or an ammonium ion. It is typically formed from the reaction of an acid with a base. Three examples of salts with their chemical formulae are: Sodium chloride: NaCl Potassium nitrate: KNO_3 Calcium sulfate: CaSO_4 2. List five uses of salts. Five uses of salts are: Food preservation* (e.g., sodium chloride for curing meat and fish). Seasoning food* (e.g., table salt, NaCl). Fertilizers* in agriculture (e.g., ammonium nitrate, potassium chloride). Manufacturing of chemicals* (e.g., sodium chloride for producing chlorine, sodium hydroxide). Medicinal purposes* (e.g., Epsom salts, MgSO_4 · 7H_2O, as a laxative). 3. What is solubility? Solubility is the maximum amount of a solute that can dissolve in a given amount of solvent at a specific temperature to form a saturated solution. It is often expressed in grams of solute per 100 grams of solvent. 4. Explain any two methods of preparing salts. For each method, give one example of a salt that can be prepared and write the corresponding chemical equation. Method 1: Neutralization (Reaction of an acid with a base) This method involves reacting an acid with a soluble base (alkali) to form a salt and water. The acid's hydrogen ions react with the base's hydroxide ions. This method is suitable for preparing soluble salts. Example: Preparation of sodium chloride (NaCl) HCl(aq) + NaOH(aq) NaCl(aq) + H_2O(l) Method 2: Reaction of an acid with a metal This method involves reacting a dilute acid with a reactive metal (above hydrogen in the reactivity series) to produce a salt and hydrogen gas. This method is suitable for preparing soluble salts of reactive metals. Example: Preparation of zinc sulfate (ZnSO_4) Zn(s) + H_2SO_4(aq) ZnSO_4(aq) + H_2(g) That's 2 down. 3 left today — send the next one.
