Calcium hydroxide

Environmental Issues Waste water generation: The wastewater produced during the chemical processes contains high concentration of chemicals such as bisulfites, sodium carbonate, sodium hydroxide, sodium sulfide, chlorine dioxide, hydrochloric acid, calcium oxide etc which is potentially unsafe to purge directly into the environment. Sludge by waste water treatment: The significant solid wastes such as lime mud, lime slaker grits, green liquor dregs, boiler and furnace ash, scrubber sludges,…

buffers and dilutes it. Through my peer-reviewed research that you can download at www.drkeithkantor.com (look at print/web) or www.namedprogram.com (go to the blog), I have found that a pure natural hydroxide (OH-) water, which is also alkaline is best. Since H+ ions cause acidity, the OH+ ions in hydroxide water search for the H+ ions to form water (H20), one of the strongest bound molecules in nature and eliminate it from the body through urination. This is the safest most natural method I…

Treatment Before I commence any treatment, I will ensure that his diabetes is controlled and it is safe to provide dental treatment. Failing to do so can result in an acute medical emergency in chair resulting from coma and ketoacidosis (Carranza, 2015). Therefore, I will refer him to his general practitioner (GP) to assess his diabetes and readjust insulin regime if required. I will update his medical history prior to treatment at each appointment. I will also ensure that I obtain written…

Single Replacement Reactions and Double Replacement Reactions A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The evolution of energy as heat and light, production of gas, formation of a precipitate, and color change are 4 indicators of a chemical reaction. Two out of the six types of reactions are the single and the double replacement reactions. During single…

drinking water is safe most of the time it still contains many contaminants. Contaminants are actually put into our water in order to kill bacteria and microorganisms that are already in the water. Liquified chlorine, fluorosilicic acid, and calcium hydroxide are just a few chemicals that are constantly added into our water. Then you have to take into consideration how many containments water gets while traveling through the pipes to you. Typical water content includes salts of radium, aluminum,…

can be added to the source water. Buffering capacity is measured in two different ways in water treatment. The first being alkalinity, which is a capacity of water to buffer or neutralize acids. The alkalinity of many surface waters consists of calcium carbonate(CaC03) content, alkalinity then is expressed in terms of mg/L of Total Alkalinity as CaC03 (Alkalinity Procedure). Carbonate can also be measured with total hardness, this generally shows the presence of carbonate not the buffering of…

reactions that occur when the cell’s surrounding is right. For instance, Heilbrunn found that the film only forms when the solvents had calcium present in it. Calcium is one of the cations; with this in mind, Heilbrunn concluded that “apparently the appearance of a film about the exuded droplet of protoplasm is due to some precipitation reaction which involves calcium” (Heilbrunn 298) He also connects that this is the same process for blood clotting in the body. There are still mysteries that…

QUESTION Explain the significance and optimum value of the following parameter i. pH ii. DO iii. TDS iv. COD v. BOD ANSWER pH ph is the concentration of hydronium ion. It represents the ratio of hydronium ions (H3O + ) to Hydroxide ion (OH- ). It is numeric scale which decides the basic and alkalinity of water. If the ph of the solution is less than 7 than then the solution is said to alkaline and if the ph is greater then 7 then the solution is said to be basic. The ph of pure water at 25o C is…

flask were stirred for a period of 15 min, and then the solution was heated to 40 , 0.5 mol p-methylcyclohexanone was introduced drop wise to the solution for about 3 h. Then the mixture was poured into 60 mL boiling water containing 2N potassium hydroxide. The solid product was separated and acidified with dilute sulphuric acid, then washed with distilled water and dried at 45 for 12 h. Recrystallization from benzene and the methanol – water system gave light yellow crystals. The synthesis of…

cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to ensure local antibiotherapy. Therefore,…
