What is ph? Principal of UV spectroscopy? Preparation of solutions like Narmal,Molar,ppm,ppb etc Definition of Chemistry, Solutions, Molality Molarity, Normality etc

Question

Accepted Answer

pH is a measure of acidity or alkalinity. UV spectroscopy is based on the absorption of UV light by molecules. Solutions can be prepared in various concentrations like normal, molar, ppm, ppb. Chemistry is the study of matter and its properties. Molality, molarity, and normality are concentration units in chemistry.

pH measures the concentration of hydrogen ions in a solution, indicating its acidity or alkalinity.
UV spectroscopy involves measuring the absorption of ultraviolet light by molecules to determine their concentration or purity.
Solutions can be prepared in different concentrations like normal (equivalent to 1 gram equivalent per liter), molar (moles of solute per liter), ppm (parts per million), and ppb (parts per billion).
Chemistry is the scientific study of matter, its properties, composition, and interactions.
Molality is the concentration of a solute in a solvent expressed in moles of solute per kilogram of solvent.
Molarity is the concentration of a solute in a solution expressed in moles of solute per liter of solution.
Normality is the concentration of a solute in a solution expressed in gram equivalents per liter of solution.
