Naming and Formulas of Acids and Bases

Mr. Spark explains the complex process of naming and writing formulas for acids and bases. The video covers the properties of acids, how to identify them, and the rules for naming them based on anion suffixes. It also details the process of writing acid formulas using the crisscross method. The video concludes with a simpler explanation of naming and writing formulas for bases, which follow the same rules as ionic compounds.

What is a key characteristic of an acid's chemical formula?

• It always ends with OH.

• It always starts with H.

• It contains a metal cation.

• It is always a solid at room temperature.

How do you name an acid when the anion ends in 'IDE'?

• Add the suffix 'ite'.

• Add the suffix 'ous'.

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

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

What suffix is used for acids when the anion ends in 'ITE'?

• 'ate'

• 'ide'

• 'ous'

• 'ic'

Which rule applies when naming an acid with an anion ending in 'ATE'?

• Use the prefix 'hydro' and suffix 'ic'.

• Use the suffix 'ous'.

• Use the prefix 'per' and suffix 'ate'.

• Use the suffix 'ic'.

What is the first step in writing the formula for an acid?

• Add a hydroxide ion.

• Identify the metal cation.

• Determine the number of oxygen atoms.

• Use the naming rule in reverse.

What is an exception to the naming rule for acids with 'ITE' anions?

• Nitrate becomes nitric acid.

• Sulfite becomes sulfurous acid.

• Sulfate becomes sulfuric acid.

• Chloride becomes chloric acid.

How are bases named compared to acids?

• Bases use the same naming rules as acids.

• Bases use the prefix 'hydro'.

• Bases are named like ionic compounds.

• Bases always start with H.

What is the formula for barium hydroxide?

• BaOH

• Ba(OH)2

• BaO2

• BaH2

What is the charge of calcium in calcium hydroxide?

• 1+

• 2-

• 2+

• 1-

What should you remember when writing formulas for bases with more than one hydroxide ion?

• Double the metal cation.

• Place the hydroxide in parentheses.

• Add a suffix to the metal.

• Use a prefix for the hydroxide.
