pH effects because it’s a chemical. The pH is adds the bleach can behave builder stabilizes subs and foam. The soap that’s been put on your skin is made up of animals, and vegetable fat. As the acids they combine there sodium and to make soap, the salt is acid. Stand in for sodium as the different types of soap they made can be formu1a remains the same as the other soap that’s have been…

spillage had not been quantified at the time of reporting, however, speculations indicated that the spillage could have been serious, thus detrimental to the environment and a threat to environmental well-being. CSX went ahead to confirm the leakage of sodium hydroxide from a derailed tanker car…

his disposal, in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of sodium chloride would react instantaneously and…

Bast was immersed in 0.85% solution of Triton X-100 at 40 ⁰C for 10 min, followed by soaking in sodium hydroxide (NaOH) solution at varies concentrations (1, 2 4, 6 and 8%) at 100 ⁰C for 60 min. For enzymatic retting, the fiber was treated with chelating agent, enthylenediamine-tetraacetic acid, then immersed in 0.85% solution of Triton X-100 at…

1.7.3.4. Hydrogen sulphid test (MacFaddine, 1980): Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production. 1.7.3.5. Sugar fermentation test (Willis, 1977): Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…

Day 2 of the experiment utilized Figure 5 to determine the metal cations present in an unknown solution #112. Each metal cation was confirmed or denied with ease, with the 2 cations present within Unknown #112 were correctly identified. Thus, Figure 5 was an accurate schematic to implement in this experiment. Following Figure 6, Unknown #112 was first added to HCl, forming a white, snow-like precipitate. The solution was decanted and separated to test the precipitate and solution, both of…

cations of cupric nitrate, ammonium nitrate, zinc nitrate, calcium nitrate, aluminum nitrate, silver nitrate, ferric nitrate, and plumbous nitrate. The other seven solutions should be the anions of sodium hydroxide, sodium carbonate, potassium sulfate, sodium iodide, sodium phosphate, sodium chloride, and sodium chromate. Divide students into groups of two. Provide a bin of paper towels for the students to empty their well plates. Students: Obtain a pair of safety goggles from the goggle…

African American women go through trial and error just to make sure their hair meet society standards. In the late 1940s, St. Paul, Minneota chemist and Jose Braquiel Calva invented the "chemical straightener", known as a hair relaxer today, has became very popular in the black communities over the years (Thompson 1). . Hair relaxers are designed to “glorify” and straighten the hair in a fast and easy process. Since the creation of hair relaxers, straight hair has been one of the many…

phenolphthalein reacting with sodium hydroxide consists of C20H14O4+ NaOH → NaKC8H4O4 (aq)+ H2O(l) Phenolphthalein is used as an indicator in this reaction because it changes color when a solution reaches a pH of around eight, or in other words the endpoint of a solution. It also allows us to see a physical change, thus resulting in a more accurate measure of how much was titrated. Citric acid is a weak acid, making it best titrated by using a strong base, such as sodium hydroxide. The…
