To find the pOH of a solution, you can use the relationship between pH and pOH, which is given by the equation: pH + pOH = 14. If the pH of the solution is 6.2, then the pOH can be calculated as follows: pOH = 14 - pH = 14 - 6.2 = 7.8. Therefore, the pOH of the solution is 7.8.
To determine which solution would require the greatest amount of base to reach a neutral pH, you would look for the solution with the lowest initial pH. For example, a strong acid solution, such as hydrochloric acid (HCl) at a low concentration (e.g., pH 1), would require significantly more base to neutralize it compared to a solution with a pH closer to neutral, like a weak acid solution. The greater the acidity (lower pH), the more base is needed to achieve a neutral pH of 7.
You would expect to find fewer hydrogen ions in the solution with a pH of 6 compared to a solution with a pH of 3. pH is a measure of the concentration of hydrogen ions in a solution, so as the pH value increases, the concentration of hydrogen ions decreases.
The pH of a solution is calculated using the formula pH = -log[H+]. Plugging in the given value of [H+] = 7.0x10^-7, you would get a pH of 6.15 for this solution.
A solution with a pH of 5 would react with a base to form a salt. The base would neutralize the acidic solution, resulting in the formation of a salt and water.
NaOH is a base so it will produce a pH above 7.
Neutral solution: pH =7Acidic solution: pH7.
The pOH of the solution would be 6. If you subtract the pOH from 14 (pH + pOH = 14), you would find that the pH of the solution is 8.
The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.
The pOH of a solution can be calculated using the formula: pOH = 14 - pH. For a solution with a pH of 6.2, the pOH would be 14 - 6.2 = 7.8.
A solution with a pH of 2 is strongly acidic. Remember, 7 is neutral, anything below 7 is acid, anything above 7 is basic or alkaline.
The pH of a solution of CaI2 would depend on the concentration of the solution. However, since CaI2 is a salt, it would dissociate in water to form Ca2+ ions and I- ions, which are not capable of directly affecting the pH of the solution. Therefore, the pH would mainly be determined by the autoionization of water.
This would be a basic solution.
The pH of a solution can be calculated using the formula: pH = -log[OH-]. Therefore, for a solution with [OH-] concentration of 10-12 M, the pH would be 12.
A solution with a pH of 7 is neutral, indicating a balance between acidic and basic properties. A solution with a pH of 9 is slightly basic, meaning it has a higher concentration of hydroxide ions compared to a neutral solution.
It would have to have a pH of greater than seven.
The pH of a 42m HCl solution would be approximately -log(42) = -1.62. This solution is strongly acidic.
To determine which solution would require the greatest amount of base to reach a neutral pH, you would look for the solution with the lowest initial pH. For example, a strong acid solution, such as hydrochloric acid (HCl) at a low concentration (e.g., pH 1), would require significantly more base to neutralize it compared to a solution with a pH closer to neutral, like a weak acid solution. The greater the acidity (lower pH), the more base is needed to achieve a neutral pH of 7.
