• A pH value below 7 indicates acidity, while a value above 7 indicates alkalinity.

• A pH of 7 is considered neutral.

• Each unit change in pH represents a tenfold change in acidity or alkalinity.

• For example, lemon juice has a pH of around 2, indicating high acidity...read more

The normal range of UV spectroscopy is typically between 200 to 400 nanometers.

• UV spectroscopy measures the absorption of ultraviolet light by a sample.

• The range of UV spectroscopy is determined by the wavelength of light used.

• The UV range is divided into three regions: UV-A (320-400 nm), UV-B (280-320 nm), and UV-C (200-280 nm).

• UV spectroscopy is commonly used in fields such as chemistry, biochemistry, and environment
