- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
-log(9.40 X 10^-4) = 3 pH
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5

pH = 6.0 at 25 oC when water equilibrium is taken into account correctly.
The concentration of hydroxide ions (OH-) in a solution with a pH of 4.0 is 1 x 10^-10 mol/L. This value can be calculated using the relationship between pH and pOH (pOH = 14 - pH), and then using the formula for the concentration of hydroxide ions in water at a given pOH.
The concentration of hydroxide ions (OH-) can be calculated from the pH using the formula: [OH-] = 10^(14 - pH). In this case, for a solution with a pH of 10, the concentration of OH- ions would be 10^(-4) M.
The pH of a solution with an H3O+ concentration of 1 x 10^-5 M is 5. This is because pH is defined as -log[H3O+], so by taking the negative logarithm of 1 x 10^-5, the pH is 5.
OH - A base. - log(1.5 X 10 -6 M) 14 - 5.8 = 8.2 pH =======
The pH of a 10^-4 M NaOH solution is around 10. This is because sodium hydroxide is a strong base that dissociates in water to produce hydroxide ions, which increase the pH of the solution.
The pH of a solution can be calculated using the formula pH = -log[H+]. Given that the hydronium ion concentration is 10^-1 M, the pH of the solution is pH = -log(10^-1) = 1. So, the pH of the solution is 1.
100,000 times more acidic
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.
The presence of an acid lowers the pH of the solution in water.
The ion that causes the pH of 10 in ammonia solution is the hydroxide ion (OH-). Ammonia (NH3) acts as a weak base and reacts with water to produce hydroxide ions, which increase the pH of the solution.
