What the PH?
negative logarithm of hydrogen ion concentration
Do buffers release H plus ions when pH increases?
No they release Negative H ions when pH increases
What is the pH value of bread?
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
Why pH can not be below 1?
It can be below 1. It can also be negative.
How calculate pH for a solution?
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
How will you classify a substance having pH value negative?
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
What is pH and how is it used?
pH is the negative logarithm of [H+] ion concentration in a given solution. pH = -log[H+] It is basically used to check the acidity or basicity of the solution. Lower the pH, more acidic is the solution. At room temperature pH=7 represents neutral solution and pH<7 or pH>7 represents acidic or basic solution respectively .
How does one calculate the pH of the solution?
The pH is the negative log of [H+].
What is the pH of iron?
Iron does not have a pH on its own. pH is the negative log concentration of H+. Iron can be affected by pH though.
PH is the negative logarithm of the?
hydrogen
What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
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 is the pH of acid?
The pH of acids ranges between 1 to 6. The one with pH 1 is the most concentrated. The pH is a measure of the concentration of H+ ions in a solution.
Can pH be negative?
There's no limit to acidity.
Are there any acids with a pH of 0?
Yes and in fact it is possible to have a slightly negative pH. Battery acid is pH 0 or close. pH is the negative logarithim to base 10 of the Hydrogen ion concentration. So 1 molar HCl has a theoretical pH of - log10[1] = 0. So 2 molar H2SO4 is slightly negative if the math is done.
Can pH be a negative number?
Yes, if the concentration of hydrogen ions is above 1 M, then pH will be negative. An example is Sulfuric acid, which can get a proton concentration up to 18 M which would be a pH of -1.3.
Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
