To find the hydronium ion concentration from pH, set base 10 to the negative power of the pH. Here that corresponds to 10 to the power of -8.75
The answer is 0.000000002 or 2x10^-9
Although this response is correct in saying that concentration and pH are based on sets of base 10; however, it is incorrect in it's response.
From pH--> [H30]
-log(pH)
From [H30]---> pH
10^(-pH)
As a chemical ion it is 'OH^-'. As in sodium hydroxide NaOH. A pH indicator will shown it as pH 8 to 12' depending on the ionic strength. A Universal Indicator will colour 'blue/violet/indigo'.
The pOH of the solution would be 6. If you subtract the pOH from 14 (pH + pOH = 14), you would find that the pH of the solution is 8.

The color produced when you add phenolphthalein to sodium hydroxide solution is pink or magenta. Phenolphthalein is commonly used as an acid-base indicator, turning pink in basic solutions with a pH greater than 8.
the lower the pH the higher the hydrogen so acid 1-6 is higher in hydrogen compared to base 8-14. 7 is neutral
A pH of 10 is 100 times stronger (higher concentration of hydroxide ions) compared to a pH of 8. This is because the pH scale is logarithmic, where each unit change represents a tenfold difference in hydrogen ion concentration.
The hydroxide ion concentration increases by a factor of 100 when the pH of a solution decreases by 2 units. This is because pH is a logarithmic scale, so each unit change represents a 10-fold difference in H+ concentration, which in turn affects the concentration of OH- ions.
If the pH is 6.00, then the pOH is 8.00 because pH + pOH = 14. pOH = 8.00 = -log[OH-] -8.00 = log[OH-] 10-8.00 = 1 × 10-8 M OH-
The pH of a solution can be calculated using the formula: pH = -log[H+]. Given the H+ concentration of 10^-8 M, the pH would be 8.
- log(1.0 X 10 -8 M)= 8 pH------------ log(1.0 X 10 -6 M)= 6 pH---------The pH lowered in solution 100 times in concentration of H +. From basic, 8 pH, to acidic, 6 pH.
The difference between a pH of 7 and a pH of 8 are as follows:A pH of 7 means the concentration of [H+] is 10-7.A pH of 8 means the concentration of [H+] is 10-8.Therefore, a substance with a pH of 8 has 1/10th the concentration of hydrogen ions that a substance with a pH of 7.
As a chemical ion it is 'OH^-'. As in sodium hydroxide NaOH. A pH indicator will shown it as pH 8 to 12' depending on the ionic strength. A Universal Indicator will colour 'blue/violet/indigo'.
The easiest definition of pH, useful at the ranges you mention, is the concentration of hydrogen ions (or univalent donors) in a solution. pH units were defined to use a log base 10 scale rather than a linear scale in order to conveniently represent an enormous range of ion concentrations. Each unit change of pH reflects a 10-fold change of ion concentration. Increasing pH was arbitrarily chosen to represent decreasing hydrogen ion concentration. Hence pH6 to ph8 is a 100x decrease in hydrogen ion concentration.
pH + pOH = 14. So pOH = 14 - 6 = 8 pOH = -log[OH-] [OH-] = 10-8 M
The pH of a solution with a hydrogen ion concentration of 10^-12 M is 12. pH is calculated as -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter. A hydrogen ion concentration of 10^-12 M corresponds to a pH of 12.
The pH of a solution with H+ concentration of 1 x 10^-8 M would be 8. This is because pH is calculated as the negative logarithm (base 10) of the hydrogen ion concentration, so pH = -log(1 x 10^-8) = 8.
Important Notice: pH = negative value of the log10 of the hyronium concentration, which is very low, mostly
