What is the function of using KHP in the COD test? (2 marks) KHP is used as a control standard because KHP is stable pure organic compounds which have the theoretical value of COD(500ppm)‚ so it can used to gain an idea of

Introduction: Since the dawn of civilization man has a close relation with nature. Man has made friendship with nature. Nature helps us in many ways. Similarly trees are closely related with our life. They are our friends. They play an important role in our life and economy. Proper place for plantation: In Bangladesh June and July are the best time for tree plantation. Bangladesh is a lower riparian country. So‚ Upper levels are the best suitable places to plant trees. Sea beaches and low lying

SAVE TREES Trees are very important for our survival in many ways. They clean the soil by filtering sewage and chemicals used in farms. They help control noise pollution and reduce flash flooding. Trees absorb carbon dioxide which contributes to global warming. They also clean the air by absorbing pollutants like carbon monoxide and sulphur dioxide. They also help to lower temperatures. They give shade during the summer and act as windbreaks during winter if they are located on the windward side

As the world is incessantly changing‚ there are many attributes which are leading towards a prosperous life but on the contrary‚ some problems are spreading of great magnitude; one of them is pollution. Pakistan is one of the developing countries which are sustaining the pollution problem.Traffic congestion is one of the main causes of air pollution. The usage of old transports is ruining the situation. No prevailing laws are strictly implemented‚ as a result‚ factories exude their smoke into the

Paramecium is a unicellular ciliate from the kingdom Protista. Paramecium can swim in the water. However‚ when you add different chemical into water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of

DISCUSSION: Qualitative analysis is used to determine the presence of cations or anions present within a sample and their impurities. Information known‚ such as chemical and physical properties‚ about cations and anions can be used to determine what steps should be used to separate the sample into one‚ specific ion. Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive‚ allowing to detect a very small amount present in sample. Due to sensitivity
