WebJan 30, 2024 · The equation to find the pH of a solution using its hydronium concentration is: pH = − log(H3O +) Using this equation, we find the pH of pure water to be 7. This is considered to be neutral on the pH scale. The pH can either go up or down depending on the change in hydronium concentration. WebIf copper is reviewed, it is seen that at a pH of 6 copper has a solubility of 20 mg/l and at a pH of 8.0, the solubility is 0.05 mg/l. Nickel has a similar curve but it occurs at 3 pH points high. At a pH of 8.0 nickel has a solubility of 70 mg/l and at …
Webis is twice that of Ba (OH)2 • ( 2 votes) phil h 3 years ago It is true that the molar ratio between Ba (OH)2 and HCL is 1:2. However, isn't the most important ratio between the H+ from HCL and OH- from the Ba (OH)2. The required amount of HCL should take into account that in the balanced equation, the ratio of the ions is 1:1? • ( 2 votes) Ryan W WebJan 30, 2024 · If pH >7, the solution is basic. The pOH should be looked in the perspective of OH-instead of H +. Whenever the value of pOH is less than 7, then it is considered basic. …

The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases.
