The purpose of this experiment was to determine the identity of nine solutions using the results of reacting pairs of solutions in an organized systematic manner. Known solutions were used on the first day. The second day, the solutions were placed in code-labeled bottles. The reactions from the previous day were then used to help identify which solutions were which, by closely monitoring which unknown solutions mixed with other unknowns and how they reacted, such as: color changes,…

What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

The reaction of soda ash (Na2CO3) with calcium sulfate in water is represented by the following chemical reaction: Na2CO3 + CaSO4 >>> CaCO3 + Na2SO4. Assuming that this reaction is complete and that there is 153 mg/l of CaSO4 initially present, what is the mass of soda ash that must be added to 1 liter of the water? How many grams of CaO are required to be the chemical equivalent of 246 g of Mg(HCO3)2? A complete reaction requires the number of CaSO4 to be equal to the number of moles…

A.2. Procedures for proper storage of the classroom chemicals General Requirements for Classroom Chemical Storage Store all chemicals inside a locked cabinet with sturdy shelves. Label cabinet with warning label and contents. Secure cabinets and shelving to the wall or floor. Segregate chemical storage away from students in a ventilated, locked storeroom. Chemical Segregation Store acids in a labeled, locked, corrosion resistant cabinet. 1 M hydrochloric acid, HCl acid; storage code: White.…

2). HEROIN: Heroin is formed by conversion of morphine which does not require complex equipmentation but more elaborate chemical operation under which morphine is refluxed with acetic anhydride for about 5 hours results into the formation of Diacetyl morphine, i.e., heroin. It is seperated when the solution gets neutralize with sodium carbonate or washing soda in which heroin gets separated as a precipitate. It is collected and purified by treating it with hydrochloric acid by which Heroin…

In this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…

with a heating mantle, mechanical stirrer, thermometer and reflux condenser, 0.5 mol of MOPE, 1.1 mol of epichlorohydrin and 300 mL of isopropanol were added to the flask. The mixture was heated to 60oC for 15 min. Subsequently 1.25 mol of sodium hydroxide in 500 mL water was…

Meta description: Potassium phosphate is a supplement that is used to treat or prevent hypophosphatemia. Potassium phosphate is an injection supplement used as a preventative in order to remedy low phosphorus in the blood. Overview Potassium phosphate is an intravenous injection used to prevent or treat hypophosphatemia, low phosphorus in the blood, through the use of a concentrated solution mixture of monobasic and dibasic potassium. Phosphorus occurs naturally in every cell in the body and…

the unknown was determined. Although there was no hypothesis made before the experiment as it was not required. With the required equipment, Hydrochloric acid was poured into a burette upto 0mL. A pipette was used to gather 25.0 cm3 of Sodium Hydroxide and transfer it into a Beaker. However during the experiment, 25.0 cm3 was converted into dm3, which resulted as 0.0250 dm3. The Beaker was placed underneath the Burette during the titration process. During the setup, a temperature probe was…

A stir bar and 4.67 mL of 2.5 M potassium hydroxide (KOH) was added into the 25-mL round-bottomed flask containing the isobornyl acetate. This flask was then attached to a water-cooled condenser and rested on top of a heating sand bath on a hotplate. The mixture remained in reflux for one hour. Then…
