Physical and Chemical Properties of Water

The physical properties of water depend on the temperature, color, taste, and smell of the water sample. The chemistry of water involves parameters such as pH and dissolved oxygen. Changes in the chemical and physical properties of water are one of the causes of water pollution.

Monitoring these characteristics helps determine whether the water meets government regulations and is safe for human consumption and the environment. Alfa Chemistry's water quality experts can evaluate the physical and chemical properties of water quality to help environmental consultants ensure that the water meets regulatory requirements and is safe for people and the environment.

Professional Water Quality Testing and Analysis

Our scientists are experienced in water analysis services and can help you evaluate the physical and chemical properties of your water samples to determine whether the water is safe and suitable for use. They are good at applying advanced technology to provide accurate and reliable results to support your experimental procedures.

Professional Water Quality Testing and Analysis

Alfa Chemistry's experts are ready to discuss with you and develop tailor-made monitoring and water quality analysis programs to meet your precise needs. We actively assist in data collection and analysis, sampling, and providing environmental reports.

Physical Characteristics of Water Quality

By monitoring the physical aspects of water quality, it can be determined whether the water is contaminated. Water has several important physical properties, which can be determined in the following ways:

  • Color - Pure water is colorless. Colored water can indicate pollution. The color can also show organic matter. The maximum acceptable level of drinking watercolor is 15 TCU (True Color Unit).
  • Turbidity - Pure water is clear and does not absorb light. If the water appears turbid, it may indicate that the water is contaminated.
  • Taste and smell - Pure water is always tasteless and tasteless. If any kind of taste or smell is present, it may indicate that the water is contaminated.
  • Solids - If the water is filtered to remove suspended solids, the solids remaining in the water represent the total dissolved solids. If the dissolved solids in the water exceed 300 mg/L, it will have an adverse effect on biological and industrial products.
  • Temperature -Temperature is not directly used to assess whether water is drinkable. However, in natural water systems such as lakes and rivers, the temperature is an important physical factor that determines water quality.

Chemistry Characteristics of Water Quality

The chemical characteristics of water involve evaluating its pH and dissolved oxygen parameters:

  • pH - The pH of water is measured between 0 and 14 to determine whether it is acidic or alkaline. Use a logarithmic scale for measurement.
  • Dissolved oxygen - It is the level of free, non-complex oxygen that exists in water or other liquids. It is an important parameter for evaluating water quality because it affects organisms living in water bodies.
