The "p" represents the "Negative Logarithm", and the "H" stands for the molar concentration of dissolved hydrogen ions. It is unknown what the "p" actually stands for, but some suggest "Power of Hydrogen" ("potenz" means power in German), other suggest it stands for "potential".

What is the meaning of pH and why is the H a capital letter?

the p stands for "negative logarithm" or -log, a mathematical function. the H is the chemical symbol for hydrogen, in the case it represent the concentration of hydrogen ions (H+) in a solution. pH is the negative logarithm of the hydrogen ion concentration or -log[H+]. This is a good measurement of acidity or alkalinity as acids increase the H+ concentration and bases decrease it.

How to calculate pH of 1N HCl solution?

The pH of a 1N HCl solution can be calculated using the formula pH = -log[H+], where [H+] is the concentration of H+ ions in the solution. For a 1N solution of HCl, the concentration of H+ ions will be 1M, so the pH will be -log(1) = 0.


How do you find H and OH when pH is known?

pH= -log[H+] (read as the concentration of hydrogen ions). Thus to find [H+], you need to determine the antilog of the reciprical of the pH. For example, if the pH is 3.76, then you need to find the antilog of -3.76 (because log[H+]=-3.76). The concentration of H+= approximately 1.74x10-4. As for OH-, we first need to establish that the negative log of a quantity is labeled p, so the concentration of OH- is expressed as pOH-, and pH+pOH=14. Here are some helpful examples: If the pH is 3, the pOH- is 11. If the pH is 5, then the pOH- is 9. So basically what you do is subtract the pH from 14 to find the pOH-. Such as in an example where the pH is 4.5. You would have 14-4.5, which equals 9.5.


What is the pH of a solution with H 2.310-6?

The pH of a solution is given by the formula pH = -log[H+]. Therefore, if the concentration of H+ ions is 2.3 x 10^-6 M, the pH of the solution would be 5.64.

What is p in pH?

pH is the scientific abbreviation for power of Hydrogen.p=power H=hydrogen. The "p" in pH comes from the notation of the probability of finding a Mole of H+ ions in a given amount of solution which is written as P(H+)=Moles of H+ per litre. Unfortunately the Probability expressed in numbers is not the ideal way to describe and compare things. The best way to do this is to have a scale and have everything fit between its extreemes. Thus the pH scale was devised where the negative log of the concentration of H+ ions gives a scale from 0 to 14. This does not mean that the definition of "p" in "pH" changed but it only says that the old name (probability of H+) is now being used to refer to the the "pH scale".

What ions do the pH scale measure?

H is for Hydrogen. p[H] is a messurement for Hydrogen-ion koncentration and pH for the activity to be correct. the p is for the -log called anti-log (log=logarithm) meaning the exponent (number of the potense) of H ions. pH = -log [H+] or [H+] = 10-pH


Why does pH make the f sound?

If you think about it really hard, pH doesn't quite make the F sound, but it's own unique sound very similar to F. Speak out loud: The P sound followed by the H sound. Keep going faster: "P---H, P--H, P-H, PH, until the two letters are closely heard next to each other. This is when you should understand why PH makes the F sound and how the letter H makes the letter P sound so much different when placed right after it. You can do the same thing with SH, TH, LK, etc. just think about it out loud.

How do you find sides of a rectangle with area and perimeter?

This is a good question, and you need to know the quadratic formula let A = area b = width h = height P = perimeter A = bh b = A/h P = 2b + 2h P = 2A/h +2h = (2h^2 + 2A)/h Ph = 2A + 2h^2 2h^2 - Ph + 2A = 0 use quadratic formula to solve: h =( P +/- SQRT(P^2 -16A))/4 This gives both sides b and h using plus then minus the square root
