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".From what I know, pH means hydrogen potential, so the p is likely to mean "potential" (of hydrogen).

"Power".
pH is the negative logarithm of the activity of the hydrogen ion in a water solution; it is used to evaluate the acidity/alkalinity of a solution.The letter H is the symbol of hydrogen; p is very probable from power.
It is 1 less. Stupid. Just kidding, remember what does the p stand for in pH? POWER of hydronium. PH is -log[H3O+], so a decrease would mean a higher concentration of Hydronium. Remember it's a logarithmic scale, so a change of 1 means a change of 10 times.
In chemistry, a lower case p means 'the negative log of-'. This means that pH is the negative log of the concentration of H+ in a solution. To put it in terms of math: pH = -log[H+]
There exist three species of alkalinity; bicarbonate, carbonate and hydroxide. The concentration of each species will vary with pH. Total alkalinity is the measurement of all species of alkalinity in the water. The concentration of each of the three species can be determined by titrating a water sample with acid of a known concentration and using chemical indicators, phenolphthalein (P indicator),methyl orange (M indicator), or a pH meter to determine "endpoints". The chemical indicators change color at a certain pH points(the endpoint). The mix of alkaline species change as pH decreases. Hydroxide alkalinity disappears below pH 10.3, carbonate below 8.3 and bicarbonate below 4.3 (or thereabout). The P indicator turns from pink to clear at or below pH 8.3 The M indicator turns from orange to yellow below pH 4.3. The amount of acid required to produce a color change is used to calculate the amount of P and M alkalinity. The P and M results are use to calculate "O" or hydroxide alkalinity. Depending on the ionic constituents of the water, these relationships can change or be interfered with.
pH (lower case "p") is the negative logrithm (to the power 10) of the hydrogen ion concentration in an aqueous solution. pH ranges from 0 to 14, with 7 being neutral, lower values acidic, and higher values basic (or alkaline).

p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH

p-ro-ph-et
p(x)=-log([x])So... pH=-log([H+])pH = 1.4
The H means hydrogen, but noone save the inventor of the pH system truly knows what the p means.
Some words that begin with the letter p and end with the letters ph:paragraphphonographphotographpictographpolygraph
p is very pobably from power and H is Hydrogen

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
