: Calculate the concentrations of hydrogen and hydroxide ions at a given pH

A Hydrogen ion (H⁺) is a Hydrogen atom (H) that has lost its (electron / proton /neutron)

A Hydrogen ion (H⁺) is basically a single (electron /proton /neutron)

A Hydroxide ion is expressed as (OH ^- / H⁺)

pH scale measures the (hydrogen / hydroxide) ion concentration of a solution.

Read and use to complete table

A neutral solution has equal amounts of H⁺ and OH ^- and a pH of 7.

An acid solution has more H⁺ than OH^- and a pH less than 7. Acids donate H⁺.

A basic (alkaline) solution has fewer H⁺ than OH^- and a pH greater than 7. Bases accept H⁺.

Fill in the blanks Table: Comparison of Acid and Base

	Acid	Base
pH greater than 7 pH less than 7
( H+) donor ( H+) acceptor
More H+ than OH- Fewer H+ than OH-
pH of 9 pH of 3

Use a pH scale to identify the following as:

neutral weak acid strong acid weak base strong base.
