determine which antacid out of the four was the most effective in terms of the one that will neutralize the larger volume of hydrochloric acid (HCl). Each type of medicine was crushed using a mortar and pestle, and then dissolved in its own beaker of 100 mL of HCl. The solution was carefully stirred to aid the dissociation process. Four drops of phenolphthalein were added to the acid. Using a burette, 4 mL of NaOH was inserted drop by drop in to the beaker, and then was continuously added in until a pale
was added in hydrochloric acid, effervescence was observed this shows CO2 is released. And then Ethanol was added to the solution for the fizzing to stop raising up. And then phenolphthalein indicator was added to the solution after the fizzing has stopped, so that the
I. Definition of a Mixture- A mixture is defined as two or more substances that are mixed together, but not held together by chemical bonds. They retain their own chemical identities and can be easily separated back to their original states using physical methods e.g. filtration, distillation. There is also little to no energy changes to the substances and have variable compositions. An example of a mixture is- Salt water (saline solution)- This mixture, containing the compounds water H20 and
appropriate process control and proper design of the reactor, the yields are optimized, leading into lower requirement of inputs and production of lower quantities of effluent. The sodium salt of p-nitrophenol is treated with concentrated sulphuric acid at 35-45°C. p-Nitrophenol is filtered. With proper filtration and water wash, alkaline liquor trapped into sodium salt of p-nitrophenol
and the vapour passes across this wetted surface, where mass transfer takes place. Packing performance is affected due to packing with different shape, different surface areas and different void space in between. Fractionator filters dilute acetic acid solution containing unreacted p-aminophenol and paracetamol in the paracetamol
