What is pH simple answer?
pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. ... Acids have a pH that is less than 7. Alkalis have a pH that is greater than 7. pH is a measure of the concentration of protons (H+) in a solution.
What is the pH level of a basic solution?
At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (e.g. pure water).
What is pH formula?
pH Calculation Formula
The formula to calculate pH is: pH = -log[H+] The brackets [] refer to molarity, M. Molarity is given in units of moles per liter of solution. In a chemistry problem, you may be given concentration in other units.
What is pH full form?
The letters pH stand for potential of hydrogen, since pH is effectively a measure of the concentration of hydrogen ions (that is, protons) in a substance. The pH scale was devised in 1923 by Danish biochemist Søren Peter Lauritz Sørensen (1868-1969).
What is the full form of pH paper?
PH: Potential of Hydrogen
It refers to the hydrogen ion concentration in a solution. It is the measure of the acidity or alkalinity of a solution. The PH value ranges from 0 to 14 on a pH scale. The PH values below 7 indicate acidity and values above 7 indicate alkalinity.
Which pH is the most acidic?
The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7.
Who discovered pH?
Søren Sørensen. In 1909 Sørensen, a Danish chemist, introduced the concept of pH as a convenient way of expressing acidity.
What is the symbol pH?
pH is an abbreviation for "power of hydrogen" where "p" is short for the German word for power, potenz and H is the element symbol for hydrogen. The H is capitalized because it is standard to capitalize element symbols. The abbreviation also works in French, with pouvoir hydrogen translating as "the power of hydrogen".
What is the pH of pure water?
Pure water has a pH of 7 and is considered “neutral” because it has neither acidic nor basic qualities.
What is the pH calculator?
pH Calculator is a free online tool that displays the pH value for the given chemical solution.
What is the kb formula?
Kb is the base dissociation constant. The base dissociation constant is a measure of how completely a base dissociates into its component ions in water. Kb = [B+][OH-]/[BOH]
