Abstract. An innovative and novel technology method of processing called Turbo-Mixing Reactive Precipitation (TMRP) design proposed as an alternative to this current processing or conventional productions of finer precipitation calcium carbonate (nano-PCC) in turbo-mixing conditions. In this paper‚ the effect of the stirring rate onto morphology‚ particle sizes and reaction time of the precipitated CaCO3 particles was discussed. CaCO3 nano particles with an average particle size of approximately

buffer against short periods of drought or to allow water supply to be maintained during transitory pollution incidents in the source river. 4. Pre-conditioning – Water rich in hardness salts is treated with soda-ash (sodium carbonate) to precipitate calcium carbonate out utilising the common-ion effect. 5. Pre-chlorination – In many plants the incoming water was chlorinated to minimise the growth of fouling organisms on the pipe-work and tanks. Because of the potential adverse quality effects

1. Define the term chemotherapy. Use of chemicals for therapeutic effect is called chemotherapy. 2. Why do we need to classify drugs in different ways ? It is useful for doctors because it provides them the whole range of drugs available for the treatment of a particular type of problem. 3. How are drugs classified? (a) On the basis of pharmacological effect For example‚ analgesics have pain killing effect. (b) On the basis of drug action It is based

Discussion Section-1 November 17‚ 2011 The other CO₂ Problem Todays oceans are not the same as they once were prior to the industrial revolution. The ocean serves as a reservoir for the worlds green house gasses. The increase in anthropogenic CO₂ has also resulted in an increase in the uptake by the ocean of CO₂. As a result of this uptake‚ the ocean is becoming progressively more and more acidic. This acidification of the ocean is expected to have great impacts on marine ecosystems. Coral

with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers remove limescale Limescale forms when hard water is heated above 61°C or when it is left to evaporate on surfaces such as taps and showerheads. Hard water is water that contains high quantities of calcium and magnesium

In this experiment‚ we took two TUMS tabs and through a back titration‚ we were able to find out how much acid was needed to neutralize two tablets of TUMS. In the first process of the titration‚ we added excess HCl and then we had to back titrate it by adding NaOH. We had to do a standardization test because the NaOH has a high reactivity and that could cause a small change. The NaOH solution was supposed to have a molar concentration of .5 however when we standardized the solution we found the
