Sodium bicarbonate

Different batch experiments were conducted to access the effect of pH on removal of heavy metals by T1B1 strain. 100 ml of sterilized SE medium was inoculated into 250 ml Erlenmeyer flask containing 100 µl (107cells/ml) of bacterial suspension with HM (mg L-1): Fe (150), Mn (100), Ni (50), Cd (30), Cu (30) and Zn (50) with pH adjusted to 4, 6.5 and 9. Another set of experiments were set up by inoculating SE medium containing HMs (mg L-1 ): Cr+6 (100, 150, 200), Fe (100, 150, 200), Ni (50, 100,…

implemented an experimental design by having the amount of sodium polyacrylate inside our superabsorbent pillow be our independent variable. We chose this variable as our treatments because the goal of our experiment was to test how the amount of…

Slime was first created in 1976 by mattel ( A toy company) it was sold in little green trash cans. It was not stretchy or soft it didn't settle, or react to touch. The original slime was not made with pva or borate it was made with guar gum and didn't have an appealing texture. Slime is now sold across the world in shops online the main seller is Etsy but other slime sellers branch out and create their own websites. Like for example GlitterSlimes (Nicolette) started on Etsy and made her own…

The hypothesis was rejected after the testing due to certain chemicals not performing what was standardized and predicted by the hypothesis. According to the overall averages, the number one most effective was Betadine with an average of 36.33mm, Hand soap was second, third was Lysol, Isopropyl alcohol scored fourth, fifth place was Germ X, and seventh had the smallest average of 7mm which was Neosporin.Betadine was expected to have a high score due to its popularity in treating wounds but the…

Badass U Articles Summary The Ultimate No More Using Soap Guide (and Never Stink) If you’ve seen my other post, you know soap is bad for your health. And, believe it or not, our bodies naturally keep odor away Our problem is when we do unnatural things…like wear clothes. But until we live in a nudist utopia, here is the ultimate guide to not using soap in our modern world. 1.) Keeping Your Clothes Clean Laundry probably seems like a no-brainer, but there is a twist here. Your skin, if you…

crystallize under such low temperature. In part II, the filtrate now contains more chloride and sodium ions, so NaCl is to be removed next. Since NaCl is the least soluble out of the four possible salts at the majority of temperatures, but does not change solubility very much with the change of temperature. Therefore, the best way to crystallize NaCl is by evaporation. Through evaporation, the concentrations of sodium ions and chloride ions increased. The concentrations of the ions were so high…

Introduction Brine shrimp are creatures that are known to thrive in harsher conditions, so they make an ideal research subject because of their durability. They are a native species of the Great Salt Lake, proving that they can withstand a high water salinity of up to 20 %+ ( https://microbewiki.kenyon.edu/index.php/Salt_Lake). Brine shrimp range from around 8-10 mm, including the tail. They have nineteen body segments, 11 of them include twenty-two legs total. Brine shrimp have an exoskeleton…

In this experiment, two cations in an unknown solution were found using qualitative analysis. For Part A, the solution was to contain either silver or lead, while in Part B, the solution that was set on the side form Part A was identified to contain either calcium or barium. Part C explored a different method through the use of cation flame tests to observe colored flames from six metal chloride solutions. In Part A, the initial step was to add HCl to the unknown sample. This was necessary…

completion. By titrating an unknown concentration of acid or base with a known concentration of acid or base, you can calculate properties such as the concentration and pKa of the analyte. During the standardization part of this reaction, we are adding Sodium Hydroxide, NaOH to a solution…

were attracted to the oxygen (negative) end of the water molecules, and the negative Cl- ions were attracted to the hydrogen (positive) end of the water molecules. As an end result, the ionic bond between the sodium and the chloride was broken. CuSO4(s) ⇔ Cu+2(aq) + SO4-2(aq) Like the sodium chloride, the copper sulphate was split into its individual ionic components. The positive Cu+2 ions were attracted to the oxygen (negative) end of the water molecules, and the negative SO4-2 ions were…
