If acid rain has lowered the pH of a particular lake from pH 7.0 to pH 4.0, the hydrogen ion concentration of this lake has been increased by a factor of 1000. This is because each whole unit on the pH scale represents a 10-fold change in acidity and basicity.

So, pH is simply -log[H+]
Hence by math, the hydrogen ion concentration is 10(-pH)
The [H+]will be 10-4 moldm-3
Have a nice day.

What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
Acidic
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
Which pH value indicates the highest concentration of hydroxide ion?
The pH scale works like this:1 being acidic, like lemon juice,10 is basic, amoniathe lower the number the more acidic, higher numbers are basic and 7 is neutralthe stronger the base, the higher the number, which means a higher OH ion concentration. the stronger the acid, the lower the number, means a higher H3O ion concentration and a lower OH concentration.
If the pH is 9 what is the concentration of hydroxide ion?
pH= -log[H+] where [H+] denotes the conc. of H+ ion. => 9= -log[H+] =>-9= log[H+] =>10-9= [H+] [OH-]= 10-14/10-9 = 10-5
What is hydroxide ion concentration if pH 8?
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 hydroxide ion concentration increases the Ph will increase or decrase?
As hydroxide concentration increases pH increases
At a pH of 7 what is true a The hydroxide ion concentration equals the hydronium ion concentration b The concentration of the acid equal the concentration of the conjugate base?
The hydroxide ion concentration equals the hydronium ion concentration at a (neutral) pH of 7
What is the difference in the amount of hydrogen ion and hydroxide ion in the solution with pH7?
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
Acidic
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What would be the pH of a solution with a hydroxide ion OH- concentration of 10-12 M?
pH 2
How does high hydroxide ion concentration do to a solution?
In this case the pH increase over 7.
How does the pOH differ from pH?
pOH happens to be the negative log of hydroxide ion' s concentration while pH is the negative log of hydrogen ion's concentration. pH is used to measure the acidity or alkalinity of a solution.
How does the POH scale form PH scale?
pH + pOH = 14 pH is a measure of the hydrogen ion concentration, [H+] pOH is a measure of the hydroxide ion concentration, [OH-] pH = -log10[H+] pOH = -log10[OH-]
What is the hydroxide ion concentration of a solution whose pH is 12.40?
2.5 x 10-2
What is the pH of a solution which has a hydroxide ion OH- concentration of 1.25 x 10-5?
9.097
What ion is in high concentration in an acid and a base on the pH scale?
In an acid (pH <7) it should be the hydronium ion: H+ or H3O+ In a base (pH >7) it should be the hydroxide/hydroxil ion: OH-
