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 is the difference between 2-pentanol from 3-pentanol?
What is the difference between 2-pentanol from 3-pentanol?
What is the pH of a solution prepared by mixing 2.0 ml of a strong acid solution of pH 3.0 and 3ml of a strong base of pH 10.0?
ph 3= [H+] = 1 x10^-3 ph 10 = pOH = 4 = [OH-] = 1 x10^-4 2 x (1 x10^-3) = 2 x10^-3 mmol H+ ions = 0.002 mmole 3 x (1 x 10^-4) = 3 x10^-4 mmol OH- ions = 0.0003 mmole H+ > OH- so subtract to get remaining OH- 0.002 - 0.0003 = 0.0017 mmole H+ find concentration [H+] = mmole H+ / ml solution = 0.0017 / (3+2) = 0.00034 M H+ now find pH pH = - log [H+] = - log(0.00034) use a calculator to find the answer.

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 :/
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.
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 of pH 3 will have 100 times more H ions than a solution of pH 5; that means it is more acidic.Note that a solution of pH 2 will have 1000 times more H ions than one of pH 2, and a solution of pH 1 will have 10000 times, etc.
What is the approximate pH level in gastric acid?
The Ph of stomach acid is between 2 Ph and 3 Ph
Is a pH of 2 stronger or weaker than a pH of 3?
Stronger
What is the pH in you stomach?
2-3
What is pH of lemonade?
2-3
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 = 3 - 1 = 2
What is the pH of 0.005M HCl?
-log10[0.01] = 2
How much more acidic is fluid with a pH of 3 more than a fluid with a pH of 7?
10^4 as each pH is equal to 10 times difference so an acid of pH 7 would be 104 weaker than an acid of pH 3
