Normality refers to the state of being normal or typical.

• Normality is a statistical concept used to describe the distribution of data.

• It is often represented by a bell-shaped curve, with the majority of data falling within one standard deviation of the mean.

• Normality is important in quality control and process improvement, as deviations from normality can indicate problems in a system.

• In chemistry, normality refers to ...read more

pH is a measure of the acidity or basicity of a solution.

• pH stands for 'potential of hydrogen'

• It is measured on a scale of 0-14

• A pH of 7 is neutral, below 7 is acidic, and above 7 is basic

• pH is important in many industries, including agriculture, medicine, and manufacturing

To prepare molar NaOH solution, dissolve the required amount of NaOH in distilled water and adjust the volume to the desired concentration.

• Calculate the required amount of NaOH using the formula: mass = molarity x volume x molecular weight

• Weigh the calculated amount of NaOH using a balance

• Dissolve the NaOH in distilled water in a volumetric flask

• Add distilled water to the flask to reach the desired volume

• Mix the soluti

Reflux ratio is the ratio of the liquid reflux to the distillate produced in a distillation column.

• It is an important parameter in distillation processes.

• It determines the efficiency of the distillation column.

• A higher reflux ratio results in a higher purity of the distillate.

• Reflux ratio can be adjusted by changing the amount of reflux liquid or the distillate flow rate.

• It is calculated as the ratio of the reflux liqu
