On the pH scale, lower numbers are more acidic, higher numbers are more basic (alkaline). 1 is the strongest acid, 14 is the strongest base, 7 is neutral.

How does the pH scale work?
pH is the negative logarithm, to the base ten, of the concentration of hydronium ions; in simple math terms, -log10[H3O+]. Another way to read this is that the concentration of hydronium is 10 to the power of pH, 10pH. It gives an indication of how many hydronium (and therefore hydrogen) ions are dissolved in the solution concerned; a larger number means less of it and vice versa.
What does the pH of a substance determine?
How acidic it is and how corrosive it is. Sulfur, for example, is 2. Battery acid is 1.
An example of a solution that has 1 solvent and 2 solutes?
give an example of a solution that has 1 solvent and 2 solutes.
What are the 2 conditions that destroy enzymatic activity by bond breakage?
1) Temperature 2)pH
How can you make solution of 2M of 800 ml from 5M solution?
In order to have a 2M solution is means that you have 2 moles for every 1 liter. Because you only want to make 800mL of this solution you only need (0.8*2) moles of or 1.6 moles of the compound in your solution. This 1.6 moles is coming from your 5M solution. So how much 5M do you need to take out to have 1.6 moles. A 5 molar solution has 5 moles for every liter, since you only need 1.6 moles of it that you need(1.6/5) liters of the solution or 0.32 liters (320 mL). Calculations done. So your going to take 320 mL of the 5M solution and put it into an 800mL volumetric flask and add water up to the line, or to be more exact, add exactly 460 mL of water in order to dilute the solution from 5M to 800mL of 2M solution.
What would be the pH of a solution with a hydroxide ion OH- concentration of 10-12 M?
pH 2
How does a solution with a pH of 2 compare to a solution with a pH of 7?
A pH 2 solution is 100,000 times more acidic than a pH 7 solution. pH 2 is acidic whereas pH 7 is neutral
How many times more basic is a solution whose pH is 12 compared to a solution whose pH is 10?
100 times. (10^2)
How many times a solution of pH 1 will be stronger than that of a solution having pH 2?
how many times a solution of ph 1 will be stronger than that of a solution having ph 2
Is a solution with a pH of 2 twice or half as acidic as a pH of 1?
No. As the pH scale is logarithmic, a solution with a pH of 1 is 10 times more acidic than a solution with a pH of 2.
How does a solution with a pH of 2 compare to a solution with a pH of 1?
A pH of 2 is 10 times more basic as something with a pH of 1
What is the pH of a solution with H plus 7.0 x 10-2?
The little 'p' means -log10 (that's the negative log to base 10). Thus pH means -log10(Hydrogen ion concentration) → pH of the solution = -log10(7.0 x 10-2) ≈ 1.15
What is the pH of a solution with h plus equals 7.0 x 10-2?
The little 'p' means -log10 (that's the negative log to base 10). Thus pH means -log10(Hydrogen ion concentration) → pH of the solution = -log10(7.0 x 10-2) ≈ 1.15
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 7.5?
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
What is the pH of 10.0L of 0.0020 M HCL?
0.002M HCl means 0.002 moles HCl in 1L solution. Therefore 0.02 moles HCl in 10L solution. pH = 2-log2 = 2-0.3010 = 1.6990
What is the pH of a 5.7 x 10-2 M solution of HI?
The little 'p' means -log10 (that's the negative log to base 10). Thus pH means -log10(Hydrogen ion concentration) → pH of the solution = -log10(7.0 x 10-2) ≈ 1.15
What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?
If concentration of Hydrogen in solution is 10-2 then its pH must be 2.
