pH=8
The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater
It depends on what the solution is. What affects the pH is the element. If there are more H+ ions in the solution you're referring to, the solution will be more acidic (lower pH). If there are more (OH)- ions in the solution, the solution will be more basic (higher pH).
ph = LOG[OH-] so.... Ph= LOG[0.170] =0.76955 H+OH = 14 so 14- 0.76955 = 13.23
pH=8
[OH-] = 3.31 log[OH-] = pOH = .51982 14-pOH = pH = 13.48
The concentration of H+ or OH-.
The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
the concentration of OH ions in solutions
Adding a base will make the pH go up (increasing of OH- ions concentration).
A solution with a pH greater than 7
Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater
It depends on what the solution is. What affects the pH is the element. If there are more H+ ions in the solution you're referring to, the solution will be more acidic (lower pH). If there are more (OH)- ions in the solution, the solution will be more basic (higher pH).
concentration of OH- is 100 times greater than what it was at PH 5
ph = LOG[OH-] so.... Ph= LOG[0.170] =0.76955 H+OH = 14 so 14- 0.76955 = 13.23
When a pH level is 7.0, it is defined as 'neutral' at 25°C because at this pH the concentration of H3O+ equals the concentration of OH− in pure water. - Wikipedia
