pH is a measure of acidity or alkalinity of a solution. It is used in various fields such as chemistry, biology, and environmental science.

• pH stands for 'potential of hydrogen'

• It is measured on a scale of 0-14, with 7 being neutral

• Solutions with a pH less than 7 are acidic, while those with a pH greater than 7 are alkaline

• pH is used in various applications such as water treatment, food and beverage production, and medi...read more

• Examples of reactions include the fight or flight response

Molarity is a measure of the concentration of a solution in terms of the number of moles of solute per liter of solution.

• Molarity is expressed in units of moles per liter (mol/L).

• It is used to describe the concentration of a solution.

• Molarity can be calculated using the formula: Molarity = moles of solute / liters of solution.

• For example, a solution containing 0.5 moles of sodium chloride in 1 liter of water has a mola...read more

Normality refers to the state of being normal or typical.

• Normality is a statistical concept that refers to the distribution of data around a central tendency.

• It is often used to describe the behavior or characteristics of a population or sample.

• Normality can be assessed using various statistical tests, such as the Shapiro-Wilk test or the Kolmogorov-Smirnov test.

• In medical terms, normality can refer to the absence of d...read more
