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.

∙ 12y agoH in pH means hydrogen and the symbol for hydrogen is a capital H so that is why it is in capitals and the p is not.
Wiki User
∙ 10y agoBecause the p is german and the h stands for hydrogen sothe p has to be lower case
Wiki User
∙ 11y agoThe abbreviation pH means "potential of Hydrogen" where capital H is the symbol for the element hydrogen.

What is the pH value of h2o?
First of all , what is 'h2o' ? If you mean 'water' , then the correct formula is 'H2O'. Note the CAPITAL letters. When expressing chemical symbols, one letter symbols are always a CAPITAL letter, hence hydrogen is 'H' not 'h'. Similarly oxygen. Two letter symbols are always written as , first letter is a Capital letter and the second letter is small/lower case. e,g, sodium (Na) neither 'na' nor 'nA'. The pH of water is '7' . It is at neutrality.
Why do the levels of pH decrease when the level of H increases?
becoz pH is the negative log of H ions. pH=-log(H+)
Does and acid with a pH of 1 or a pH of 3 have a greater H concentration?
A pH of 1 has a higher H+ concentration
If a solution has a hydrogen ion concentration of 10-5M what is its pH?
The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
What have the smallest number hydrogen ions pH 2 or pH 6?
pH = 6 is the answer. For pH = 2, [H+] = 10-2 For pH = 6, [H+] = 10-6
How does the concentration of H affect the number on the pH scale?
The meaning of a higher H+ concentration is a low pH.
Why is there a lower case p before a capital letter H in the scientific symbol pH?
yes and it means the negative logarithim to base 10
How do you write capital h a?
To write "Capital H a", you would simply write the letter "H" followed by the lowercase letter "a".
Is h a symmetrical letter?
No but capital H is a symmetrical letter

What does the h stand for in pH scale?
The letter h in pH scale stands for Hydrogen. The proper description for the name ph. is potential of Hydrogen.
What does the scientific meaning for the word pH?
pH refers to the relative concentration of H+ ions in solution.
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
Capital city start with letter H?
US capital cities starting with the letter "H"Harrisburg, PennsylvaniaHartford, ConnecticutHelena, MontanaHonolulu, HawaiiHouston, Texas
What type of polygon is the block letter h?
The block capital letter H is a 12 sided polygon.
What state and its capital both have names that begin with the letter H?
The state of Hawaii and its capital Honolulu both start with H.
How many lines of symmetry does a letter h have?
Capital H has 2 lower case h has none
