Vinegar is a clear liquid that is made up of acetic acid (HC2H3O2)‚ and water (H2O). This solution is common in an average household for it is used for cooking and cleaning. By definition‚ a titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Titrations are performed in chemistry‚ along with different manufacturing companies‚ to help determine the concentrations of acids and bases when they are unknown‚ when a neutralization

After an initial lag in 1973 and 1974‚ when large surpluses were saved and invested abroad‚ consolidated public expenditure accelerated rapidly: by 1976 it absorbed the entire oil windfall (Figure 2). By 1977 combined federation and states capital expenditure increased six fold over their 1970 level. Public capital expenditure accelerated so strongly that it alone accounted for the spending of more than half of the entire oil windfall. However‚ Nigeria’s continued failure to improve its ranking

Introduction- Can a filter be made for the polluted water so the water will have a clarity of 0%. If a filter is built for the polluted water‚ then the waters clarity will be 0% and the pH value will be 7. The purpose for this lab is to get the polluted water to a clarity of 0%. Water pollution is playing a major role in today’s ecosystems because the water is becoming unsafe to live in and unsafe to consume. “Water pollution is any physical or chemical change in water that adversely affects organisms”

Procedure: The addition of 4.0 mL cyclohexanol‚ 1.0 mL of 85% phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate

According to my forensic teams research‚ the evidence sample contained starch. My team was also able to determine that the evidence sample dissolved in water ‚and felt like a powder. Performing different tests helped to determine the ingredients that the evidence consisted of. First‚ my team performed a water test‚ by mixing drops of water with the substances A through E and the evidence sample. The forensics then conducted a vinegar test and an iodine test‚ to test for Co² and starch. Finally‚ a
