The goal of this research was to build a technique to independent a mixture of sand, salt, straightener filings, gasoline and drinking water.
It was hypothesized the heterogeneous mixture of salt, crushed stone kerosene, iron fillings and water will be effectively segregated. It is also forecasted that you will see a reduction in each of the chemicals as a effects of options for error.
Risk | Control Measure
Glass- Fragile, cuts could take place | Extra care was taken, safety gloves worn once handling. Enclosed shoes donned. | Kerosene- skin annoyance, eye annoyance, hazardous in the event that inhaled or digested. Remarkably flammable. | Lab clothes, safety spectacles, extra treatment was used when handling and has not been placed near any face parts. Kept away from fire at all times. | Sand- skin and vision irritant| Lab coats and safety eyeglasses worn | Salt- epidermis and attention irritant | Lab clothes and security glasses worn| Iron fillings- dangerous to ingest | Extra treatment when considered. Was not put near jaws. | Bunsen burner- Open fire: serious melts away could take place, hazardous to surroundings. | Was not positioned near any flammable fluids. Heatproof pad used, Security flame on when unattended, extra treatment taken.
1 gram of crushed stone, salt and iron filings were weighed out accurately and the results were recorded and noted. 50mL of gasoline and 50mL of normal water were also measured and by using a measuring cyndrical tube. The components were all thoroughly mixed collectively to ensure that any soluble substances were dissolved. A magnetic was placed over the blend to magnetize the iron fillings. The iron filings were after that collected and weighed. The mixture after that had been through filtration to remove the sound particles of sand. The sand was then gathered and measured. A separating funnel utilized to separate the kerosene in the mixture, the kerosene was then put into a computing cylinder and the loss of liquid was mentioned. The salt blended in normal water was evaporated to obtain a...
