2024年10月23日 · The pH value of household items can vary widely depending on the specific product. For example, vinegar typically has a pH of around 2-3, making it acidic, while baking soda has a pH of around 9 ...

2024年5月25日 · The pH of a 3.0 M solution of KOH (potassium hydroxide) would be very high, around 13-14. This is because KOH is a strong base that completely dissociates in solution to release hydroxide ions ...

2024年6月2日 · Methyl orange is not suitable for acid-base titrations because its color change occurs over a broad pH range (pH 3.1 to 4.4), making it less precise for determining the endpoint of the titration.

2024年5月21日 · The pH or potential of hydrogen is the figure that expresses the alkalinity and acidity of a solution which 7 is the neutral scale. The pH of the solution containing 100m HONH2 and 100m HONH3CL is ...

2024年5月30日 · The pH of a 3M KCl solution would be very close to 7, which represents neutrality. This is because KCl is a neutral salt and does not significantly affect the pH of the solution.

2024年6月11日 · Since you know the molecular mass of KCl is 74.55, that can be set up as a fraction: 74.55 grams/ 1 mole. You want a 3 molar solution and (for simplicity sake) you want 1 Liter. This can be ...

2024年6月1日 · The pH of a 0.005N HCl solution is approximately 2.3. This is because HCl is a strong acid that dissociates completely in water to form H+ ions, leading to an acidic pH. What is the pH of 0.25 M HCl?

2024年5月21日 · What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 75? pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.

2024年6月5日 · Iodine does not have a pH since it is not an aqueous solution. pH is a measure of the concentration of hydrogen ions in a solution.

2024年11月24日 · Oh, dude, the pH of a 1.0 x 10^-3 M KOH solution is 11.00. Basically, you take the negative logarithm of the concentration of hydroxide ions in the solution to find the pH.
