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 is the abbreviation of PH?
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.
How does a pH reading of 5 differ from 6?
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.
Relation between pH value and H ions?
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+]
What is different between hardness and alkalinity?
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.

Is Providencia stuartii gram positive or gram negative?
its gram negative
Who first used p in pH?
madam curie
What does pH indicator?
p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH

What is the pH of a 4.3 x 10-2 M HCl is the solution?
p(x)=-log([x])So... pH=-log([H+])pH = 1.4
What does the acronym pH?
The H means hydrogen, but noone save the inventor of the pH system truly knows what the p means.
