Calcium hydroxide

Nifedipine Nifedipine is a common drug used to treat a variety of disorders from hypertension and angina to preventing premature labour in pregnancy (Aedla, N, et al. 2012). It originated in the early 1970’s from the works of Bayer, who developed the short-acting formulation that proved to be successful in controlling high blood pressure, however due to its side effects, was modified to a long-acting formula which produced fewer side effects and is commonly used in modern obstetric practice…

result of a trauma or mechanical problem. The direct exposure must have a pin-point size. Calcium hydroxide is the prevalent used as pulp capping in addition to the new surrogate mineral trioxide. Direct pulp capping aids in healing of the pulp and in the formation of reparative dentin.…

main aim of the experiment is to find out the percentage of calcium carbonate in toothpaste by using back titration since calcium carbonate is an insoluble salt and does not dissolve in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed at the end point.…

Calcium chlorate is a very dangerous chemical. It has the ability to harm whoever is around it. It is important to be extremely cautious and pay close attention to what you are doing when working with this product. This chemical may seem a bit scary because of the negative effects it can have on a person, but there are good things about it too! Calcium chlorate is produced on an industrial scale. It is produced by the chlorination of milk of lime. It is produced by passing chlorine gas through a…

(Sr) and it has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons. The electron configuration of Strontium is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 5s^(2) or…

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…

precipitate, indicating sulfate ions' presence; see Table 2 of week 1 for results. Then we moved on to our cation test; this test involved a pH test, flame test, and more reaction tests. In one of our tests, we reacted ammonium nitrate with sodium hydroxide to create a solution; then, we tested the solution with pH and turmeric powder, which…

A COMPARATIVE EVALUATION OF ANTIMICROBIAL EFFICACY OF ALOE VERA , SESAME OIL AND TEA TREE OIL AGAINST E. faecalis - AN IN-VITRO STUDY” INTRODUCTION Medical microbiology entered a new era towards the end of the nineteenth century. It was during these golden years that path-breaking work of Pasteur, Koch and others in the development of broth and agar media led to the ability to grow a majority of pathogenic micro-organisms which were deemed uncultivable…

1. Calcium is the fifth common element in the earth’s crust, and is found predominantly in feldspar, calcite, dolomite, and apatite, as a primary and secondary mineral. Calcium is found in lime stone but is also added as lime and in fertilizers. However, Calcium is not added as the soil is insufficient in Calcium, but to increase the pH. Calcium is a macro-nutrient which is essential in plant growth, the functioning of root tips, and is a main constituent in the cell wall. The amount of Calcium…

1. Which impurity particles are larger, the one causing the water to be cloudy or the one causing the water to smell? Explain. The common problems with water are colors, smells and tastes. First, there are several problems of colors. Brown, red, orange, or yellow water is usually caused by rust. The different colors can be attributed to varying chemical oxidation states of the iron (rust) and by varying concentrations of the rust in the water. Moreover, blue or green color is generally a result…
