Acids and Bases Naming and Characteristics

The video tutorial explains how to identify and name acids and bases. It covers the identification of acids by the presence of hydrogen ions and bases by hydroxide ions. The tutorial details the naming conventions for oxyacids, such as phosphoric acid, and binary acids, like hydrobromic acid. It also explains how to write formulas for bases using the crisscross rule, exemplified by magnesium hydroxide.

What is a common characteristic of acids in terms of their chemical formula?

• They end with OH.

• They start with a hydrogen ion.

• They contain a metal ion.

• They have a neutral pH.

How do you name an oxyacid that contains a polyatomic ion ending in '-ate'?

• Change '-ate' to '-ous' and add 'acid'.

• Change '-ate' to '-ic' and add 'acid'.

• Add 'hydro-' prefix and '-ic' suffix.

• Add 'per-' prefix and '-ate' suffix.

What is the charge of the phosphate ion in H3PO4?

• 3-

Which of the following is NOT a rule for naming acids with polyatomic ions?

When writing the formula for magnesium hydroxide, why are parentheses used around OH?

• To show it is a polyatomic ion.

• To denote it is a metal.

• To indicate it is a single element.

• To highlight it is an acid.

How do you determine the number of hydroxide ions needed to balance a magnesium ion in a compound?

• Check the pH level.
