2024年10月23日 · The pH values of common household items are: Lemon juice: pH around 2 Vinegar: pH around 3 Milk: pH around 6-7 Baking soda solution: pH around 8-9 Ammonia …

2024年5月26日 · This is because nitric acid (HNO3) is a strong acid that dissociates completely in water to release H+ ions, causing a high concentration of H+ ions in the solution and a low pH …

2024年5月29日 · By looking it up on wolframalpha, I find that for every mole of H3PO4 In the solution, 1.06 moles of H+ are present. So if I take the -log1.06, I find the pH of 1M phosphoric …

2024年6月16日 · At a certain temperature where the pH of a neutral solution is 7.56, the value of Kw (the ion product of water) can be calculated using the equation Kw = [H+] x [OH-].

2024年5月28日 · The pH of a 2M HNO3 solution is approximately 0. This is because nitric acid (HNO3) is a strong acid that fully dissociates in water to release H+ ions, resulting in a highly …

2024年6月17日 · The pH of a 1 millimolar NaOH solution is approximately 11. The concentration of a 1 millimolar solution is 0.001 mol/L, and NaOH is a strong base that completely …

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.

2024年5月26日 · A pH of 6.5 is slightly acidic. On the pH scale, which ranges from 0 to 14, values below 7 are considered acidic. A pH of 7 is considered neutral, while values above 7 are …

2024年5月29日 · The pH of 0.25 M HCl is approximately 0.6. This is because HCl is a strong acid that dissociates completely in water to give H+ ions, resulting in a highly acidic solution.

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.
