Understanding Acids and Their Nomenclature

The video tutorial explains the definitions and classifications of acids, focusing on binary and oxy acids. It details how to recognize and name these acids based on their chemical formulas. Binary acids consist of hydrogen and a non-metal, while oxy acids include oxygen. The tutorial provides examples and mnemonic devices to aid in understanding the naming conventions, emphasizing the importance of recognizing oxyanions and their charges.

What is the primary characteristic of acids according to the definition used in the video?

• They do not react with metals.

• They are always solid at room temperature.

• They form ions when dissolved in water.

• They are ionic compounds.

How can you recognize a binary acid from its chemical formula?

• It ends with 'OH'.

• It contains oxygen.

• It starts with 'H' and contains only two elements.

• It contains a metal and a non-metal.

Why is water not named as an acid despite starting with 'H'?

• Because it is not a binary acid.

• Because it is a solid.

• Because it can act as both an acid and a base.

• Because it contains oxygen.

What is the correct name for the binary acid HF?

• Hydrochloric acid

• Hydrosulfuric acid

• Hydrofluoric acid

• Hydrobromic acid

What is the key difference between binary acids and oxy acids?

• Binary acids are always stronger than oxy acids.

• Oxy acids contain oxygen, while binary acids do not.

• Oxy acids are always stronger than binary acids.

• Binary acids contain oxygen, while oxy acids do not.

How do you name an oxy acid if the oxyanion ends in 'ate'?

• Add 'hydro' and change 'ate' to 'ous'.

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

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

• Add 'hydro' and change 'ate' to 'ic'.

What mnemonic device is suggested for remembering the naming rules for oxy acids?

• Rick ate him before he could bite us.

• The quick brown fox jumps over the lazy dog.

• Every good boy does fine.

• My very educated mother just served us noodles.

What is the name of the acid with the formula HNO3?

• Nitrous acid

• Nitric acid

• Acetic acid

• Sulfuric acid

Which of the following is an example of an oxy acid?

• HF

• HCl

• HBr

• H2SO4

What is the formula for periodic acid?

• HClO4

• HIO4

• H2SO4

• HNO3
