Hydrochloric acid

If a quantitative solution needs to be prepared, there are a series of steps that must be followed in order to get accurate answers. there are several objects needed to prepare it, including a 500 ml graduated cylinder, deionized water, and sodium phosphate dodecahydrate as the aqueous solution. The first step is to find the mass of the solution, sodium phosphate. In the formula, sodium's atomic mass is multiplied by 3 because there is the original weight times 3 atoms of sodium in the formula.…

Who will use the Thermoller? People that loves playing sports in hot weathers. People from places that is hot. This device is mainly foe emergency use and can cool water in a situation where there is no ice. This can also be used to carry food around, keeping them hot or cold the way a thermos does. How does the Thermoller work? The Thermoller is activated by water. The packaging will include a funnel for using purposes (it will also include a bag that you can carry the Thermoller in). When you…

Chapter 2 LITERATURE SURVEY 2.1. Characteristics of Hydrogen Sulphide 2.1.1. Physical and Chemical Properties H2S is a colourless gas characterised by a rotten gas odour which is highly toxic. It is soluble in different liquids including water and alcohols. It is typically formed under deficit oxygen conditions in the presence of organic matter and sulphate compounds (WHO, 2003). Hydrogen Sulphide is also present in the atmosphere in the range of 0.0001-0.0002 ppm though it may vary with places…

Paragraph 1 This report aims to study the symmetrical distinctions, crystal structures and chemistry of α‐FePO4 and β‐FePO4 as well as any alteration to FeO4 and PO4 when there are modifications to temperature. It also seeks to justify the tilting of the tetrahedral. The article by Haines shows that he had studied the iron phosphate, FePO4, at temperatures from 294 K to 1073 K and had found that the turning point between the 2 phases is at 980 K, where FePO4 takes on the alpha phase at…

observed that all the experiments are majorly based on several reactions. Firstly, reaction between hydrogen peroxide and acidified potassium iodide is the first stage reaction which is obtained from reaction between potassium iodide and sulphuric acid. 2KJ+H2SO4→2HJ+K2SO4 H2O2+2H++2J-→2H2O+J2 At the second stage, reaction between Na2S2O3 iodine. If little amount of Na2S2O3 is used then it cut down the iodine produce to iodine ions.…

Introduction The purpose of this lab is to find the emperical formula of a compound made of magnesium and oxygen. We took a strip of magnesium and combusted it to figure out how much of the strip was magnesium by weighing the remaining ashes. The weight that wasn’t transferred to ashes was burnt off in the smoke as oxygen. To find the emperical formula, you had to take the average mass of both magnesium and oxygen and divide by the average mass to get the amount of mols in the compound.…

DEVIATION BACKGROUND: On 07/28/2017, During the inspection of PRODUCT A on TP- 18, while the operator was transferring the coated tablets into a plastic scoop, which is used to load the coated tablets into the printer product hopper during the printing, what appeared to be a live and small gnat fly was observed inside the product bag. This was discovered after the operator pulled the product liner off the coated drum to pour the remaining tablets into the scoop. Per routine procedure, during…

mechanochemical method was employed to synthesis CP and MgCP where calcium hydroxide (CaOH2), phosphoric acid (H3PO4) and magnesium hydroxide (MgOH2) were used as precursors. Table 3.1 shows the parameter used by varying the weight percentages (wt. %) of Mg. Table 3.1: The weight percentages ratio for magnesium doped calcium phosphate Samples Parameter Calcium Hydroxide Ca(OH)2 (g) Phosphoric Acid H2PH03 (g) Magnesium Hydroxide Mg(OH)2 (g) Undoped CP 27.7 22.3 0.00 1.0wt.% 27.7 22.3 0.50…

The hypothesis that increasing the sucrose concentration from 6% (m/v) to 12 (m/v) would increase the rate of fermentation was not supported by the experiment. When looking at the graph it can be seen that the data obtained provided unclear results. Rather than the fermentation rate being significantly faster with a 12% (m/v) sucrose concentration throughout the entire study; the graph showed the fermentation rate for 12% (m/v) sucrose concentration was faster at times while the fermentation…
