ph scale

what a ph scale

• measure of how acidic/basic water is

• really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

• whereas a pH of greater than 7 indicates a base.

how do you use a ph scale

• The pH scale measures whether there is more hydronium or hydroxide in a solution.

• In other words, it tells us how basic or acidic the solution is.

• A higher pH means it is more alkaline or a stronger base.

what is acid on the ph scale

• As this diagram shows, pH ranges from 0 to 14, with 7 being neutral

• .while pHs greater than 7 are alkaline (basic

• pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

what is the range of the ph scale

• The range goes from 0 - 14, with 7 being neutral.

• pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

• pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

what does ph scale stand for

• The range goes from 0 - 14, with 7 being neutral.

• pH is a measure of how acidic/basic water is

• pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

what year did they come up with the ph scale

• 2007

• 2006

• 1909

who created the ph scale

• Søren Sørensen

• Danish chemis

why was the ph scale invented

• just to miss people up

• as a convenient way of expressing acidity.

What are the most important uses of the pH scale?

• the chemical conditions of a solution

• iological functions, microbial activity

What is pH scale write its uses and importance?
