Those solutions contain various concentrations of (free) H+ ions:
1.0*10-2 = 0.010 M, 1.0*10-3 = 0.0010 M and 1.0*10-6 = 0.000,0010 M.

What has a pH of about 3?
Substances with a pH level of below 7 are said to be acidic and substances above the pH level of 7 are alkaline. An example of a substance with the pH of about 3 is orange juice.
What is the pH of 0.005M HCl?
-log10[0.01] = 2
What is the color of phenolphthalein in solutions with pH values ranging from 2 to 6?
A typical aqueous solution containing phenolpthalein is colorless within the pH range 2 - 6.
What pH are the following eight substances - lemon juice- ammonia cleaner- salt water- tap water- vinegar- tea- bicarbonate of soda- and milk of magnesia tea?
Lemon juice: pH around 2: ammonia cleaner: pH around 11-12; salt water: pH around 7; tap water: pH around 7; vinegar: pH around 2-3; tea: pH around 4-6; bicarbonate of soda: pH around 8-9; milk of magnesia: pH around 10.
Black coffee has a pH of 5 and milk magnesia has a pH of 10 Is coffee twice as acididc as milk of magnesia?
No, the pH scale is logarithmic, not linear. A difference of 1 on the pH scale represents a tenfold difference in acidity or basicity. So, coffee with a pH of 5 is actually 100 times more acidic than milk of magnesia with a pH of 10.
What has a pH of about 3?
Substances with a pH level of below 7 are said to be acidic and substances above the pH level of 7 are alkaline. An example of a substance with the pH of about 3 is orange juice.
What is the difference between a pH of 2 and a pH of 4?
The answer is 2 ^^the above is TOTALLY wrong! the difference between say pH 2 and pH 3 is a difference of 10...im not sure if the difference of pH 2 and pH 4 is 100 or 20 because im not sure if you add the 10's or if you multiply them...but the answer is deffiently either 100 or 20...sorry i didnt help much :/
Is a pH of 2 stronger or weaker than a pH of 3?
A pH of 2 is stronger (more acidic) than a pH of 3. The pH scale is logarithmic, meaning each whole number change represents a tenfold difference in acidity.
What has a pH of 3?
A substance with a pH of 3 is considered to be acidic. Examples of substances with a pH of 3 include lemon juice and vinegar.
On the pH scale a solution with a pH of 3 is?
A solution with a pH of 3 will be acidic. Substances with pH's below 7 are termed acidic, those with pH's higher than 7 are termed basic or alkaline.
What has a pH level of 3?
A substance with a pH level of 3 would be considered acidic. Examples of substances with a pH of 3 include vinegar and orange juice.
Where does lemon juice lie on the pH scale?
Lemonade has a pH of about 2 or 3. Acidic substances have pH's below 7 and while bases have pH's above 7. Pure water (deionized) has a pH of 7.0. (Tap water is generally slightly acidic with a pH of ~6.5).
If a solution has a pH of 3 does it have more or less H ions than a solution with a pH of 5?
A solution with a pH of 3 has more hydrogen ions (H+) than a solution with a pH of 5 because the pH scale is logarithmic, so each unit change represents a tenfold difference in hydrogen ion concentration. A lower pH value indicates a higher concentration of hydrogen ions.
What are common liquids with PH level of 1 With PH level of 2 PH level of 3 PH level of 4?
Common liquids with a pH level of 1 include battery acid. Liquids with a pH level of 2 can include lemon juice or vinegar. At a pH level of 3, liquids like orange juice or soda may be present. With a pH level of 4, substances like tomato juice or beer can be found.
If stomach acid has a PH of 1 and a person took a tums tablet which raised the PH to 3 how much was the increase in PH?
The increase in pH would be 2, as going from a pH of 1 to a pH of 3 represents a change of 2 pH units.
What are items that have a pH value?
Items that have a pH value include: lemon juice (pH 2), baking soda (pH 9), vinegar (pH 3), milk (pH 6.5-6.7), and bleach (pH 12-13). Each of these substances falls within a range on the pH scale from acidic to basic.
What is alkalis acid?
Alkalis are bases that are substances with a pH greater than 7. They are known for their ability to neutralize acids. Acids, on the other hand, are substances with a pH less than 7 and can donate hydrogen ions in a chemical reaction.
