Answer 1

Bases are typically ionic compounds that produce hydroxide ions in water, with CsOH being an example of a base. Lithium hydroxide is an ionic solid, and acids with the suffix '-ous' have less oxygen compared to those with '-ic'.

Step-by-step explanation:

Understanding Bases and Acids in Chemistry

1. Bases are typically ionic compounds as they consist of metal cations and hydroxide anions. Acids can be molecular, but when they dissolve in water, they often form ions. Therefore, the true statement among the given options is that bases are ionic compounds.

2. Among the options provided, CsOH is a base. It is composed of cesium, which is an alkali metal, and hydroxide ion, and it dissociates completely in water to produce hydroxide ions.

3. A base like lithium hydroxide (LiOH) is an ionic solid. This is because it is made up of a metal cation (lithium) and a hydroxide anion, fitting the profile of an ionic compound.

4. Acids with the suffix '-ous' contain less oxygen than their counterparts with the suffix '-ic'. For example, sulfurous acid (H2SO3) has one less oxygen atom than sulfuric acid (H2SO4).

Answer 2

Question 4

Explanation

If the acid has more oxygens, it usually ends with -ic i.e H2SO4 which is sulphuric acid, H3PO4 is phosphic acid. The acids with less oxygens end with -ous.

Answer

less oxygen
