The meaning of PH is a measure of acidity and alkalinity of a solution that is a number on a scale on which a value of 7 represents neutrality and lower numbers indicate increasing acidity and higher numbers increasing alkalinity and on which each unit o
Water exists as an equilibrium between molecules and ions: H2O ⇌ H+ + OH- The multiplication product of the concentrations [H+] and [OH-] is a constant; it is water's dissociation constant, which has a known value of 10-14 M2. Kw = [H+][OH-] = 10-14 M2 For neutrality, [...

pH scaleThe fundamentals of acids and bases and how the pH scale is used to measure them. See all videos for this article Because of uncertainty about the physical significance of the hydrogen ion concentration, the definition of the pH is an operational one; i.e., it is based on a meth...
pH is usually to measure acidic or basic water is. pH is a measure of the relative amount of free hydrogen and hydroxyl ions in water. There are 0-14 range to be measure which is 7 is for neutral while pH which less that 7 is acidity and the pH which is greater than 7 is alkali...
For most purposes the difference between the two scales for dilute aqueous solutionscan be ignored; it depends on the density of water, and is about 0.001 at 298.15 K risingto 0.02 at 393.15 K.1.2 Operational definition. It is universally agreed that the definition of pH differ-ence is an ...
To determine the pH of water, a pH meter can be used to measure this important water quality parameter.
The water quality regulations specify that the tap water should have a pH level of 6.5 to 9.5. Water leaving the treatment works should have a pH of 7 and 9. However, this can change as it passes through the network of water mains and reservoirs. We consume various beverages and foods...
The meaning of PHREATOPHYTE is a deep-rooted plant that obtains its water from the water table or the layer of soil just above it.
The International Union of Pure and Applied Chemistry (IUPAC) has a slightly different pH scale based on electrochemical measurements of a standardbuffer solution. Essentially, the definition uses the equation: pH = -log aH+ where aH+stands for hydrogen activity, which is the effective concentration...
