The pH scale is logarithmic, with lower numbers being more acidic. So the difference between the two is 9-2 = 7. The pH 2 is 10^7 (10 million) times more acidic.
Actually the pH number which is between 7 & 14 is considered alkaline or basic.
No. of hydrogen ions = 1 x 10-2 moles No. of hydroxide ions = 1 x 10-12 moles
There are 1010 more moles of hydrogen ions than hydroxide ions.
10,000 being that every step you move in the pH scale is ten times more than the previous one.
The pH scale is logarhythmic, therefore, a difference of 4 points of pH corresponds to a difference of 10,000 times the concentration of hydrogen ions.
To find the concentration of hydrogen ions in a solution, you use this formula:
[H+] = 10-pH
Using this formula, we find that the concentration of hydrogen is 1.0 x 10-2 M.
The concentration of hydrogen ions is higher.
Since [H+] x [OH-] = 10^-14 and from a pH of 2, this tells you [H+] = 10^-2, therefore [OH-] must be 10^-12. So, that's what you can say about H+ and OH- ions.
You mean hydronium ions. Its 0.01 mol/L
You get a basic solution with pH above 7. It contains more OH- ions than H+ ions
A lower pH means more hydronium; each decrease by 1 means the concentration is increased tenfold. You would expect to find fewer hydrogen ions in the pH 6 solution (1000 times fewer ions).
If a solution containing A+ ions and a solution containing B- ions have just been mixed and [A+][B-] is greater thanKsp of AB, _____.
Because of the logarithmic nature of the pH scale, a single step indicates a difference tenfold. As such, the difference in concentration of hydrogen ions between solutions A and B in this example are a hundred fold, with solution A having a higher concentration than solution B.
A basic solution has greater concentrations of OH- than H+ ions. The opposite is acidic. An easy mnemonic device for this is that you want to get an A+ not a B-.
A million
it has more hydroxide ions than hydronium ions
10 times as many
In a solution with a pH higher than 7, there are more hydroxide than hydrogen ions.
1,000,000 X more
1
An acidic solution contains many more H+ ions than OH- ions, and a basic solution has more OH- than H+. A pure water solution, which is neutral, has exactly equal number of each.
More hydroxil ions.
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).
the more hydroxide ions releases, the more basic the solution becomes. and the solution has more hydroxide ions than hydrogen ions.
acidic
Ten times.
