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
The pH of a solution containing 3.0 g of HI in 500 ml of water is approximately 1.7.
Avicel pH 102 is typically used as a pH buffer in pharmaceutical formulations. It is commonly used in the range of pH 5.5 to 7.5, but the exact pH can vary depending on the specific formulation and conditions.
Potassium iodide (KI) is considered a neutral solution because it dissociates in water to form potassium ions (K^+) and iodide ions (I^-), which do not affect the pH of the solution. The ions from KI do not contribute to the acidity or basicity of the solution, meaning that KI does not alter the pH level significantly.
Neutral solution: pH =7Acidic solution: pH7.
No, any solution with a pH over 7 is alkaline.

An acidic solution has a pH under 7 and a basic solution has a pH over 7.
A pH 7 solution is neutral, indicating a balance of acidic and basic components, while a pH 10 solution is basic, meaning it has a higher concentration of hydroxide ions. The pH scale is logarithmic, so a pH 10 solution is 1000 times more basic than a pH 7 solution.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
To measure pH accurately in a solution, you can use a pH meter or pH strips. A pH meter provides a digital reading of the pH level, while pH strips change color based on the pH level of the solution. Simply dip the pH meter probe or pH strip into the solution and read the pH value indicated.
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.
A PH of 4 makes the solution acidic
The pH is a measure of the acidity/alkalinity of a solution.
