What is the pH of solution 2?

3.8
The pH of « Solution 1″is 3.5 and the pH of « Solution 2 » is 3.8.

Is a pH of 4 twice as strong as a pH of 2?

Since 10-2 = (100)10-4, the concentration of [H3O+] is 100 times as great at pH = 2 than at pH = 4, so the acid is 100 times as strong at pH = 2 than at pH = 4.

What is a pH of 4?

A pH less than 7 is acidic. A pH greater than 7 is basic. 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 times (10 times 10) more acidic than pH 6.

What is the difference between pH 1 and 2?

PH-1 is a One-pole Electrode. PH-2 is a Two-pole Electrode, with a ground electrode and an operation electrode. Use PH-1 for liquids that contain a large amount of foreign matter. Use PH-2 for liquids that do not contain a large amount of foreign matter because it is more convenient.

How do you find the pH of two solutions?

For example, if the components of a two-acid solution provide 0.025 and 0.015 mol of hydrogen ions (H+), respectively, and the mixed solution has a volume of 200 ml, the concentration will be 0.040 mol divided by 200 ml – or 0.0002 mol of H+. The -log of this concentration, and the pH, would then be 3.699.

Is a base above 7?

The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. … As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

How many times has a solution of pH 2?

The pH scale is logarithmic and as a result, each whole pH value is ten times more acidic than the next higher value. pH 2 is (10 x 10 x 10 x 10 x 10 x 10) or 1,000,000 times more acidic than pH 7. 100 times. The pH scale is logarithmic, so each step is a factor of 10.

What is a pH of 6?

A pH of 7 indicates a neutral solution, a pH greater than 7 indicates a basic solution, and a pH of less than 7 indicates an acidic solution. The farther a pH value is from 7, the more strongly acidic or basic it is. For example, water with a pH of 6 is mildly acidic, and water with a pH of 3 is highly acidic.

Is 1 acidic or basic?

Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline. The blood in your veins is slightly alkaline (pH = 7.4). The environment in your stomach is highly acidic (pH = 1 to 2).

What substance has a pH of 2?

  • Strong bases have very high pHs (sodium hydroxide, commonly known as lye, has a pH of 14). Lemon juice has a pH of 2; vinegar of 2.5; coffee of 5; distilled water of 7; borax of 9; and household ammonia of 11.

Is pH of 2 very acidic?

  • For instance, water coming out of an abandoned coal mine can have a pH of 2, which is very acidic and would definitely affect any fish crazy enough to try to live in it! By using the logarithm scale, this mine-drainage water would be 100,000 times more acidic than neutral water — so stay out of abandoned mines .

What is the pH of Ca(OH)2?

  • pH of a saturated solution of Ca (OH)2 is 9. The solubility product (Ksp) of Ca (OH)2 is: pH of a saturated solution of Ca (OH)2 is 9. The solubility product (Ksp) of Ca (OH)2 is:
