pH Levels

between 7 and 8

To answer this question we would need to know the type of drain cleaner you are referring to. If you are talking about liquid drain cleaner it has a pH of 14. But the pH ranges from 13 to 14 depending on the type.

Pepsin doesn't affect the pH but it is active in an acidic environment.

The pH of a laxative, is up the but and around the corner. Just playing its 3 degrees.

The hepatic Bile has a pH of about 7.4 and the Bladder bile has a pH of about 6.8.

On an average the pH of bile juice is between 6.8 and 7.6.

Adding water does not always decrease pH. pH is a measure of the concentration of hydrogen ions, also called hydronium ions. They are inversely related. More hydrogen ions means a lower pH.

A base has a pH greater than 7 (neutral) because it has an increased amount of hydroxide ions which causes a lower amount of hydrogen ions. Adding more water to a base solution causes the concentration of the hydroxide ions to become less, thus due to equilibrium, causing the hydrogen ion concentration to increase. This does cause pH to become less ... decrease.

But an acid solution does the exact opposite when water is added. It already has a large concentration of hydrogen ions, but as water is added the concentration decreases and this causes pH to increase.

Granular potassium sulfate does not have a pH. A pH value can only be given to a solution.

the concentration of hydrogen ions - H+

the pH level decreases or becomes more acidic

When anything is neutralized, the pH value moves closer to 7. In addition, when a weak acid is being neutralized, a buffer is also being formed, until all the weak acid has been converted to the salt.

basic--above pH 7.0

acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride

Aproximatly 3.4 - 4.1

0-6 and everything less than 7 (grade 7 science)

The pH of a weak base can be anything greater than 7.0. Generally, weak bases do have a lower pH that strong bases, but this is not always true. The fact that a base is weak only means that it does not completely ionize in solution. The pH of a weak base depends only upon the concentration of hydroxide ions (OH-) in solution.

the pH of cranberries is 4.

1-6

This is a basic pH.

The pH of Orange Juice is 3, meaning it's very acidic. The concentration of Hydrogen ions is 10-3 m/L.

pH= 6.9 - 7.1 on average.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

very acidic . neutral ... very basic

The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.

pH is a measure of the acidity/or alkalinity of a substance. Substances that are more acidic have a lower pH value. It may help you to remember if you think of the pH scale as a measure of alkalinity (the opposite of acidity), that way, as the numbers get bigger the alkalinity increases. Acidity is due to the presence of hydrogen ions within the substance, and a greater concentration of hydrogen ions will cause something to be more acidic.

pH is commonly measured by introducing the substance to a pH strip, and comparing the color the strip turns against a scale provided with the strip. A pH strip is a piece of paper in which is embedded some substance that reacts to a certain level of acidity by changing color. Litmus is perhaps the most famous pH indicator (thus the expression of applying a litmus test) and will turn red at a pH below 4.5 and blue above 8.3. There are a number of other substances that change color at a specific acidity. A very accurate pH test strip works by embedding some of these substances in the strip so that different substances will change color, thus reveling the acidity of the substance.

its about 10.5 to 11

come on people i need to know i am really stuck wiv ma omework
