Water filter

total of four mixtures present in the whole activity. This is because the main mixture which is the salt, sand, chalk, and water mixture can’t be separated using only one separation technique; it should be separated by parts. First, a filter paper was used to separate the salt and water from the chalk and sand. is the filtration process, a separation technique using a filter paper to separate solid particles in a liquid. Second, acid dissolution, using HCl (Hydrochloric acid) that will react…

However, it can produce both asexually and sexually. The sponge reproducing sexually is much more common than it producing asexually. Sexual spawn happens when a male sponge shoots sperm into the water, and with luck, it will reach a female. Asexual spawn happen when a piece of the Yellow Tube Sponge breaks off, during a storm or whatnot, and lands somewhere hard, like a rock. It then sustains a life of its own. It cannot truly care for its young…

Exactly 5.00 mL of milk was pipetted into a clean 250 mL Erlenmeyer flask and 100 mL of distilled water was added, as well as 10 mL of buffer solution, 1 mL MgEDTA, and 5-6 drops of Eriochrome Black T indicator. The initial volume of the EDTA in the burette was recorded and then the titration started and continued until the sample solution changed colors…

was not entirely pure. The sucrose could have been contaminated by another compound or residual diethyl ether may not have evaporated from the very bottom of the tube. To only dissolve the sucrose water could be added. Neither the carboxylic acid nor the neutral compound would be soluble in water, so the sucrose could be isolated.…

recrystallization, and melting point determination. Procedure: 1. In the first step we have to brew a very strong cup of tea. Bring in two tea bags from home. Bring about 100 ml of water to boil in a 150 ml beaker. Add about tip of spatula full of sodium carbonate. Place the tea bags in the boiling water and let them steep for 7 - 10 minutes with a watch glass on the top and the heat on low. Excessive heat can decompose caffeine so do not let the tea dry out. 2. Squeeze the tea bag…

Boil the ash with about 20cmᶟ of purified water in a beaker, and filter while hot. Collect the clear filtrate in a second beaker and allow to cool. We then placed the ash into distilled water and allowed it to boil once again over the Bunsen burner to allow the extraction of iodine to begin once this has complete all the iodine can be extracted from the water using a funnel. Ensure that the beaker is allowed a sufficient amount of time to cool before…

For our diffusion experiment our group decided to work with salt water and gummy bears. Our experiment tested the weight of the gummy bears per salt dilutions. Our tests included 1g 2.5g 5g, 1.5g, and 10g of salt diluted with water. We knew that the higher the concentration of salt diluted into the water the heavier the diffused gummy bear would be, therefore we measure weight as our numerical data. My hypothesis was that the 10g dilution of salt would have the gummy bear with the largest…

feed. The mass of usable starch after extraction was calculated to be 1125 kg/h. In addition, the mass of water was calculated to be almost 4700 kg/h. Non-extractable starch, as well as proteins, fibers, minerals and vitamins were considered to be separated out from the starch-water solution, as they have no practical use in this bio-ethanol production process. After extraction, the starch-water slurry will be fed into a starch hydrolysis unit. Although not considered in detail, the hydrolysis…

theoretically our end product mass should have been 0.52 grams. The reasoning behind our error in mass for this part of the experiment could be because we did not allow the water to completely filter out of our product. The added water weight could account for our high percent yield at the end of the experiment, had we allowed our product to filter out for a longer period of time we may have had a more accurate mass. In experiment 2 our group, along with the other groups, ended up with a greater…

portable water purifier, an axe, and a satellite phone. I am confident I will be able to sustain on the island, and lastly getting rescued by the civilization. Considering that I will need safe drinking water, edible food, and a safe shelter. The portable water purifier is essential, and it should be your first priority; next having a sharp axe can be extremely convenient; and lastly I am going to bring a satellite phone so I can be rescued in time. Seeing that drinkable water is…
