15.0 mL of 1M aqueous sodium hydroxide was added to the clove oil in the separatory funnel. The bottom layer of the separatory funnel was removed and the top layer added to a 250 mL beaker. The aqueous bottom layer was then added back to the separatory funnel. 15.0 mL of 1M aqueous sodium hydroxide was added to the separatory funnel. The bottom layer was again removed and the top layer added to the previous 250 mL beaker. 10 mL of hydrochloric acid was added

loosely applied as the flow properties of drilling mud. The relative viscosity‚ or the cuttings carrying ability of the drilling fluid‚ can be measured by the Marsh Funnel. This comparative measurement is performed by simply recording the number of seconds required for a given volume of drilling fluid to pass through the Marsh Funnel.

A stemmed funnel lined with a filter was clamped and placed into a 125mL separatory funnel (with stopcock closed). The spinach was crushed with a pestle until it turned a dark green

groundwater‚ it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants by using a funnel to purify the water. The last experiment were performed using Dasani‚ and Fiji bottled water and Tap water to determine the quality of drinking water. I also predicted that tap water would leave the least amount of contaminants and the Fiji bottled

Determination of soil inhabitants was done using Berlese-Tullgren apparatus. The obtained data concurred with the accepted general climate and soil condition of the selected premise. Soil exhibits a generally slightly basic nature‚ moist to dry‚ with relatively high temperature.Significant differences

MANUAL Q3: The stopper on top of the separatory funnel creates a vacuum seal on the funnel‚ which is what allows the solution to drip out slowly when the stopcock is open. Therefore‚ to drain out an entire layer efficiently from the funnel‚ it is best to remove the stopper. Finally‚ pour the remaining top layer into a new 125 mL Erlenmeyer flask. Discard both flasks of solutions after getting

Organisms are open systems that interact continuously with their environment. The study of the interaction between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from

Materials: * Dialysis(cellulose) tubing * Thistle funnel * Gas jar * Retort clamp and stand * Rubber bands * 50mL beaker * Iodine/potassium iodine solution * 5% starch solution Method: 1) Fill the gas jar to 3 quarters full with water. Add iodine solution until the water is quite yellow/brown. 2) Moisten the cellulose tubing and tie a knot at 1 end. At the other end insert the stem of the thistle funnel & fasten it firmly with a rubber band. 3) Fill

There was a few things I have learned and things that had helped with my project. One of the things I’ve learned is that the funnel is one of the things that takes up lots of time for our project. I think that without the funnel‚ our project will likely fail. Also‚ one of the things that help our project is the track. The track help the marble roll down all the way to the big funnel‚ but friction. Another thing that help our project are the ramps. The ramps are one of the important things that helped
