Give the name or chemical formula, as appropriate, for each of the following acids: (b) HBr

Verified step by step guidance

1. Identify the type of compound: HBr is a binary acid, which consists of hydrogen and one other nonmetal element.
2. Recognize the pattern for naming binary acids: Binary acids are named using the prefix 'hydro-', followed by the root of the nonmetal element, and ending with the suffix '-ic acid'.
3. Determine the root of the nonmetal element: The nonmetal in HBr is bromine, so the root is 'brom'.
4. Apply the naming pattern: Combine the prefix 'hydro-', the root 'brom', and the suffix '-ic acid' to form the name.
5. Conclude with the name: The name of the acid HBr is hydrobromic acid.

Key Concepts

Acids and Their Properties

Acids are substances that can donate protons (H⁺ ions) in a solution. They typically have a sour taste and can conduct electricity when dissolved in water. The strength of an acid is determined by its ability to dissociate in water, with strong acids completely ionizing and weak acids partially ionizing.

Naming Acids

The naming of acids depends on the anion present in the compound. For binary acids, which consist of hydrogen and one other nonmetal, the name is formed by using the prefix 'hydro-', followed by the root of the nonmetal's name, and ending with 'ic acid'. For example, HBr is named hydrobromic acid.

Chemical Formulas

A chemical formula represents the composition of a substance, indicating the types and numbers of atoms present. For acids, the formula typically starts with hydrogen (H) followed by the anion. In the case of HBr, the formula indicates one hydrogen atom and one bromine atom, reflecting its identity as a binary acid.
