In its most basic form pH = -log[H+] where [H+] is the concentration of hydrogen ions from the acid dissocating.
Given the acid dissocation constant and an inital concentration of the acid we can calculate [H+]
the most common calculation you will see when doing the maths is Ka[inital acid concentration] = [x2]
from this we get [H+] and sub into the first equation to get pH.
From pH we can get pOH, as pH + pOH = 14
From pOH we can get the antilog and calculate [OH-]

pH is a measure of the acidity or basicity of a solution. It is measured on a scale from 0 to 14, with 7 being neutral. Lower values indicate acidity, while higher values indicate alkalinity. pH can be measured using a pH meter or pH paper.

∙ 13y agoThe pH of something is negative logarithm of the concentration of the hydrogen ions.
Basically...
log101/10,000,000 = -log1010,000,000
This means 10 to the power of what is 10000000. 107 = 10,000,000. So the pH is 7.

∙ 15y agoThe short answer is to take the negative log of the concentration of Hydrogen atoms in solution (ie the concentration of the acid itself, if monoprotic), this is usually sufficient for strong acids that dissociate completely. For weaker acids you usually need to use the acid dissociation constant Ka of the acid at various levels of ionization. Once you've calculated the amount of H+ ions dissociated by the acid, you can use the negative log of that concentration to determine pH. The calculations are too lengthy to be provided here, but are available in most basic chemistry texts and online tutorials.

∙ 14y agopH is a measurement you can not add it to water. Messing around with the pH of water containing fish can be a very dangerous thing to do. If you wish to increase or raise the pH from being acid you will need to add some form of alkaline substance like Sodium Bicarbonate ( NaHCO3) that is available at most pet shops.

∙ 13y agopH is the negative log10 of the hydrogen (H+) (or hydronium: H3O+) ion concentration (moles/liter). Find the concentration, and it's then a very simple mathematical operation.
So if the hydronium ion concentration is 10-7 moles/liter then pH = -log10(10-7) = 7. See related link.

∙ 13y agotest it with Universal indicator, BTB or litmus paper. =)
Wiki User
∙ 8y agoOne way is to get litmus paper, and dip it in your solution. The paper will turn the colour of the colour associated with the ph
Wiki User
∙ 8y agoRather than litmus paper, which will only indicate acid or base, use pH test paper, or a pH meter.

What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 75?
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
How you can test the pH of solution?
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
Which ranges on the pH scale are acidic basic and neutral?
Acidic: pH less than 7 Neutral: pH of 7 Basic: pH greater than 7
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 7.5?
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
Which is the most acidic pH 2 pH 5 pH 7 or pH 11?
The most acidic pH among the options given is pH 2. pH values below 7 indicate acidity, with lower values being more acidic.
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 75?
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
What solutions is the weakest acid pH of 2.4 pH of 5.2 pH of 6.4 pH of 8.6 or pH of 10.1?
pH=6,4
Do you use pH or PH?
neither pH

How do we find out the pH?
The pH is determined with a pH-meter.
Which ranges on the pH scale are acidic basic and neutral?
Acidic: pH less than 7 Neutral: pH of 7 Basic: pH greater than 7
What pH values indicates a solution with the highest concentration of hydrogen ions pH equals 1 or pH equals 2 or Ph equals 7or pH equals 14?
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 7.5?
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
Which is the most acidic pH 2 pH 5 pH 7 or pH 11?
The most acidic pH among the options given is pH 2. pH values below 7 indicate acidity, with lower values being more acidic.
What can be used to get a pH value?
A pH meter or pH test strips can be used to measure the pH value of a solution. pH meters provide a numerical value of the pH, while pH test strips change color based on the pH level of the solution, allowing for an approximation of the pH value.
What is the pH of tomatoes ketchup?
The pH of tomato ketchup is 3.85
What are some ways to determine the pH of a liquid?
Some ways to determine the pH of a liquid include using pH test strips, pH meters, or pH indicator solutions. pH test strips change color based on the acidity or alkalinity of the liquid, pH meters provide a numerical pH value, and pH indicator solutions change color to indicate the pH level.
