Calcium hydroxide

abnormal tissue structure. As bones become less dense, they weaken and are more likely to break. This occurs from a lack of calcium and phosphate. Calcium is essential for properly functioning the heart, brain, and other organs. Keeping up with those critical demands of those organs, the body reabsorbs calcium that is stored in the bones to maintain calcium blood levels. If calcium isn’t sufficient…

In the Acid-Catalyzed Hydration of norbornene, water and sulfuric acid were added to the C=C double bond to form norborneol. Sulfuric acid acted as a catalyst, where it was not consumed in the reaction and helped to propel the reaction forward, as it was vital in forming hydronium ion and breaking the double bond. Both the products endo-norborneol and exo-norborneol were synthesized; however regioselectivity and stereoselectivity played a role as to which product was more preferred and whether…

The learning assistants for Professor Bahde’s Organic Chemistry I class, Allyson Dang and I, wanted to give the students a problem to work on involving a reaction mechanism. The students in that class have been struggling in many areas of the subject, but the main issue they have is drawing out reaction mechanisms. Knowing how to draw out reaction mechanisms is one of the most, if not the most important part of organic chemistry. When theoretically reacting molecules, one must know not only…

has more hydrogen ions, it is an acidic solution, and if the solution has more hydroxide ions, it is a base (636). Acids and bases can be strong or weak. Strong acids are able to conduct electricity, and all the HCl molecules in the solution can be ionized completely (644). Weak acids produce fewer ions, and therefore do not conduct electricity well (645). Strong bases can dissociate completely into metal ions and hydroxide ions, while weak bases can only ionize partially (648). This means…

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…

product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions could be used in this experiment to eliminate compounds while attempting to identify others. Halides react with AgNO3 to form insoluble halides. These ions form white-yellow precipitates that enable differentiation. Ag+ + NO3 - + M+ + X- = AgX + MNO3 Precipitates…

solution, because it is the source of the Grignard reagent. Because the halide cannot be eliminated, the next best option is to minimize the amount of halide in the reaction. In this experiment, a small concentration of the halide is reacted with a high concentration of magnesium to ensure maximum contact between halides and magnesium. To do this, magnesium will be placed in the round bottom flask and then halides are slowly added. Another potential source of error is that Grignard reagents must…

Alcalak, and Medi-first were indirectly titrated with sodium hydroxide (NaOH), which is a strong base. By using the back titration technique, the amount…

Purpose What makes the best bubble solution? In order to make a best bubble solution, I have to use detergent, corn syrup, water, and glycerin. By the best, I mean a mixture that creates a solution which will last long. Acknowledgments I would like to thank everyone who helped me make my project successful. First of all, I would like to thank my teacher Mr. Mackey’s help. He provided the instructions and explained how to do an essay and a poster board. Secondly, I would like to thank you my…

Firstly we need to recognize what hard water is, hard water is a water that has high mineral substance. Hard water happens when groundwater grabs minerals as it moves through rock and soil. It most normally grabs salts like magnesium chloride and calcium chloride. At the point when hard water is utilized to wash your dishes, it might turn out looking more regrettable than when they went in. Hard water leaves your dishes spotted and can even keep your dishes from getting as perfect as they…
