In this lesson, we will learn how to calculate the pH of a solution and describe the ion-product constant of water.

Students will be able to

recall the pH scale and identify the pH of acids, bases, and neutral solutions,
recall that water can self-ionize to produce and ions,
write and describe the equation for the ion-product constant of liquid water, Kw,
define pH in quantitative terms as ,
relate Kw to pH and pOH,
calculate and/or from pH and/or pOH,
calculate pH and/or pOH from and/or .
