pH+scale

**What is the pH scale?

The pH scale is the scale you use to figure out the ampunt of acid in the water. It is a scale with a rating of** **0-14, 0 being very acidic and 6 in acidic but not as high. 7 is netural. 8-14 is base which is not always good. [1]

This is a picture of a (new, up to date) pH probe, used to measure acidic, netural, or base liquid. [2] The pH number you recieve after measuring the pH is used to tell what types of fish can live in the water you measured. This is a picture of (old) way to measure the pH. You would dip them into the liquid, wait 30 seconds. and then find the color the strip turned on the bottle.[3] **

A substance that is neither acidic nor basic is neutral. <span style="FONT-FAMILY: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode','Lucida Grande',sans-serif">The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. <span style="FONT-FAMILY: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode','Lucida Grande',sans-serif">The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8. <span style="FONT-FAMILY: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="FONT-FAMILY: 'Lucida Console',Monaco,monospace"><span style="FONT-FAMILY: 'Lucida Sans Unicode','Lucida Grande',sans-serif"> Pure water is neutral. But when chemicals are mixed with water, the mixture can become either acidic or basic. Examples of acidic substances are vinegar and lemon juice. Lye, milk of magnesia, and ammonia are examples of basic substances. [5]

The pH scale is a scale that measures the acidity of a body of water. the scale ranges from 0-14. 0-5.9 meaasn the water is too acidic. If the pH is between 6.0-8.0 then the water is nuetral which is safe for fish to live in. if the water has a pH of 8.1-14 then the water is too basic.[6] "Acidic and basic are two extremes that describe a chemical property chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. A substance that is neither acidic nor basic is neutral."[7]
