Sun Flag Steel Interview Questions and Answers

A spectrometer is a scientific instrument used to measure properties of light over a specific portion of the electromagnetic spectrum.

• Spectrometers work by separating light into its different wavelengths or frequencies.

• They can be used to analyze the chemical composition of substances, identify unknown materials, and measure the concentration of substances.

• Different types of spectrometers include UV-Vis spectrometers, ...read more

pH value of acid indicates its acidity level on a scale of 0 to 14.

• pH value of acid ranges from 0 to 6.9 on the pH scale

• Lower pH values indicate stronger acidity

• Examples of acidic substances with pH values: lemon juice (pH 2), vinegar (pH 3)
