The pH scale is a Science indicator, Not a Mathmatical one :-)
The pH scale is a measurement system that indicates the concentration of Hydrogen ions also called Protons.
Hydrogen ions
this is false they dont measure Hydrogen ions
what yeah you just got schooled son
pH is a measure of the ion H+ activity in a solution.
The pH is a measure of the the ion H+ concentration.
Hydrogen ions
Hydrogen ions
H+ ions
True
The pH scale represents the relative concentration of hydrogen ions in a solution. The concentration of hydrogen ions is commonly expressed in terms of the pH scale. Low pH corresponds to high hydrogen ion concentration and vice versa. A substance that when added to water increases the concentration of hydrogen ions (lowers the pH) is called an acid. A substance that reduces the concentration of hydrogen ions(raises the pH) is called a base. Finally some substances enable solutions to resist pH changes when an acid or base is added. Such substances are called buffers. Buffers are very important in helping organisms maintain a relatively constant pH. The pH scale is a scientific classification of how acidic or basic a substance is. The scale ranges form 0 to 14 -- a pH reading of 7 is neutral in nature , a pH less than 7 is acidic in nature and a pH greater than 7 is basic in nature.
they use the pH scale
Normally term,'PH' of a solution is used determine the strength of an acid which is nothing but the concentration of H+ ion concentration in a solution. ph= -log[H+] concentration.... since its -ve log hence smaller value of PH means it's more strong acid. ph=7 is value of water which is neutral. pH ranging below 7 are acids & above 7 are bases.
pH scale ranges from 0 - 14. It measures the acidity or basicity of a solution. A measurement of 7 is neutral, less than 7 is acidic and a basic is higher than 7. pH is measured based on the concentration of hydroxide and hydrogen (or hydronium) ions in solution. A solution containing hydrogen (H+ ions) or Hydronium ions (H3O - which is made from the reaction of hydrogen ions with water) indicate a pH lower than 7 or an acidic solution. A solution containing hydroxide ions (OH-) creates a basic solution with a pH greater than 7. It is possible to measure a pH that is greater than the bounds of the scale since the calculation for the scale is based on the negative log of the concentration of hydrogen (or hydronium) ions in the solution. pH=-log[H3O] therefore [H3O] = 10^-pH
The pH scale.
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
pH + pOH = 14 pH is a measure of the hydrogen ion concentration, [H+] pOH is a measure of the hydroxide ion concentration, [OH-] pH = -log10[H+] pOH = -log10[OH-]
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
The pH scale (not hP) is used to measure the acidity/basicity of an aqueous solution. It actually is a measure of the hydronium ion concentration. pH <7 is acidic; pH>7 is basic; pH=7 is neutral.
pH
pH is a measure of the acidity of the solution. It describes the concentration of H+ or H3O+ ions in a solution. pH= -log10[H+]. Therefore, the lower the pH, the higher the concentration of hydrogen atoms and the more acidic the solution.
Yes, if you use a little bit of math. Take 14 minus your pH and you get the negative decadic logarithm of the hydroxide concentration.
pH value(not the 'unit' just the scale)
pH is a measure of Hydrogen concentration pH = -log10[H+], where [H+] is the concentration of hydrogen ions. From this equation, we can see that an increase of hydrogen ions will lower the pH, and a decrease of hydrogen ions will raise the pH. =D
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
The measure of the H+ concentration is the pH.
The meaning of a higher H+ concentration is a low pH.
