How to write an acid formula?
Understand the Problem
The question is asking for guidance on how to write the chemical formula for an acid, indicating a need for knowledge in chemistry related to acid nomenclature and formula construction.
Answer
Combine hydrogen with an anion. For binary acids, use 'hydro-' and '-ic'. For ternary acids, use '-ic' for anions ending in '-ate' and '-ous' for anions ending in '-ite'.
The formula for an acid combines hydrogen (H) with an anion. For binary acids, it uses 'hydro-' prefix and '-ic' suffix. For ternary acids, if the anion ends in '-ate' it uses '-ic', and if it ends in '-ite', it uses '-ous'. Example: HCl is hydrochloric acid, H2SO4 is sulfuric acid.
Answer for screen readers
The formula for an acid combines hydrogen (H) with an anion. For binary acids, it uses 'hydro-' prefix and '-ic' suffix. For ternary acids, if the anion ends in '-ate' it uses '-ic', and if it ends in '-ite', it uses '-ous'. Example: HCl is hydrochloric acid, H2SO4 is sulfuric acid.
More Information
Understanding how to write acid formulas requires recognizing patterns in naming conventions and how hydrogen pairs with other ions or elements.
Tips
A common mistake is confusing the suffixes '-ic' and '-ous' for ternary acids. Remember '-ic' for anions ending in '-ate' and '-ous' for anions ending in '-ite'.
