Distilled water

sweating but water just isn't enough you need something more like a sports drink. When you exercise a lot you lose salts in your body that need to be replenished with a new salt which are known as electrolytes. Why do the sports drinks make you feel awake? The reason is simple, the drinks contain these electrolytes which are like a food for the cells in your body. Amazingly these can also be found in batteries. Why isn't water just as good as a sports drink for replenishing your lost water?…

substance with known-concentration and then determining the unknown concentration. There are two ways to get the standardized solutions: A primary standard – is a precisely measured on a balance and therefore moles of a solid substance dissolved in a water. Then it…

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…

a lid for each cup and taped it to the sides so the seal would be as tight as we could make it. We also needed a 150mL beaker to measure out the 50 mL of distilled water that we used in each trial to dissolve each compound in. To weigh out each compound we also needed an electronic balance. After each compound was added to the 50mL of water we used a magnetic stirrer and a stir plate to dissolve the compound and then a thermometer to measure both the initial and final temperatures of the…

cylinders after. Sustaining all variables unaffected such as the pH, same size, and a constant temperature. Hypothesis: I predict if there is more water potential in the cylinder the potato’s mass will increase. Materials • 1 Cork Borer (0.9 c) • 1 Scalpel • 1 White Tile • 1 Clear Plastic ruler (±0.1 cm) • 25 test tubes • 120 ml of distilled water • 5 Stopwatches (± 0.1s) • Electric…

17.1 g sucrose and 100mL deionized water in a flask. After 1 week, the ethanol solution was distilled and collected. The reaction was demonstrated as below: C12H22O11 (s) + H2O (l)…

will affect the the freezing point the most. The freezing point of a liquid is, the point of a substance when the temperature of the solid and the liquid is equal. When water freezes the water molecules become organized and come closer together forming crystal particles of ice.When a solute (like salt) and a solvent (like water) mix together the salt becomes an impurity and makes it so the solution can’t crystallize. This means that the solution remains liquid even when the temperature…

soxhlet extraction method for 8 hours by using Methanol is 50% while Hexane is 81.82%. The oil extracted from microwave assisted extraction method for 1 hour by using distilled water is 59%. The volume of distilled water used was up 350 mL in order to make sure the reaction was smoothly occur in the 500 mL round bottom…

pipette was used to measure 1 mL of concentrated nitric acid into a 10 mL graduated cylinder. The concentrated nitric acid was placed into a reaction tube and clamped in the water bath. In step four, 1 mL of concentrated sulfuric acid was added slowly to the traction tube with nitric acid. Then the mixture was left to sit in the ice water bath for at least five minutes. A small plastic bag was filled with ice and a towel was wrapped around the bag. A towel was used to wrap the bag to insure that…

Traditional titration with indicator dye (week one) First the 50mL buret was cleaned by filling it with distilled water and letting it empty three separate times. It was further cleaned by coating the inside with 5 to 10 mL of the 0.0468M NaOH titrant solution and emptying that into the waste beaker as well for three repetitions. 40.0 mL of 7-Up soda was diluted with 60.0 mL of distilled water in a graduated cylinder, and the solution was quantitatively transferred to a 250 mL flask with 5 drops…
