CHEMICAL WASTE MANAGEMENT IN DEVELOPING COUNTRIES INTRODUCTION Chemical waste is managed in various ways‚ some which are environment friendly and some which are hazardous. It has effects on water supply‚ fertility of the soil‚ climate‚ health of individuals‚ et.c. What really matters is how well this waste is managed. Chemical waste management typically includes the collection‚ transportation‚ processing and recycling/disposal of chemical waste. In past times‚ it was the role of the country to

Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes

The current industrial agriculture system promotes the reliance on agrochemicals‚ both synthetic fertilizers and pesticides‚ while neglecting to consider their negative effects on the economy of local communities‚ human health and the environment. The widespread use of irrigation‚ agrochemicals and new seeds have largely increased agriculture production‚ but this model of agricultural growth is flawed because of declining

Data Tables: Part 1: Chemicals Well No. Observations of the Reaction A. NaHCO3 + HCl A1 Bubbles immediately formed and started popping (not rapidly). This could be seen more easily with the black paper underneath the well plate B. HCl + BTB C1 Once I added the Bromothymol Blue indicator‚ it turned an orange-like color C. NH3 + BTB E1 The reaction turned dark blue. When Bromothymol Blue reacts with an acid‚ it turned orange‚ and when it reacts with a base‚ the end result is blue. D. HCl
