Calcium hydroxide

Marshmallows were once of the first ever sweet treats to ever be made. Originally, marshmallows were made from the root sap of the Athea Officinalis. They are called marshmallows because part of the recipe called for the sap from root. This plant’s root was soft, spongy and sticky, just like a marshmallow. This plant grows in swampy fields. People used to use marshmallows as medical treatments. They were used to clear sore throats and the Romans used them for fights. In the mid 1800s people…

Titanium bones are the implants that doctors use when a bone is broken to badly to heal naturally. The natural way for a bone to heal is in a cast and take time for the bone to heal but titanium implants help the bones that can not do that. Titanium is used in the body because it is lightweight, sturdy and it would last long because it is durable. Titanium bones have been worn away with time especially at the hip and elbow joints but scientist are working on a way for titanium bones to become a…

2.1.2. Alkaline hydrolysis Alkaline hydrolysis is a simple process in which the protein is solubilized by heating followed by the addition of calcium, sodium or potassium hydroxide as alkaline agents and maintaining the temperature at a range between 25-55 °C (Pasupuleti & Braun, 2010). During alkaline hydrolysis of proteins, some amino acids like serine and threonine are damaged during alkaline hydrolysis, however, tryptophan remains intact. Also, this process causes racemization of amino acids…

produced during the fermentation is around 12-14% because as the alcohol content get higher, the yeast culture will die and the fermentation process will be stopped 3. If carbon dioxide, the gas product of the fermentation, was to react with calcium hydroxide instead of water, a precipitate CaCO3 will form. The reaction would happen as follow: Ca(OH)2 (l) + CO2 (g) → CaCO3 (s) + H2O…

temperature but have a low melting point and are very soft. An example of this would be potassium which can be cut with a knife. However, these metals are extremely reactive with water. When placed in water they produce hydrogen gas, heat and metal hydroxide. The salts in this group are very soluble in water because they have large ions and low densities that can easily be separated. This can be seen when salt (Na) is mixed with water and begins to dissolve forming salt water. Salt also happens…

Material and Method ================ The practical course of the present study was implemented in the farm ofFaculty of Agriculture,Minia University, Minia Governorate. 2.1. Animals: The present study was conducted on twelve healthy Osemi rams, 4 months old, located at the farm of Faculty of Agriculture, Minia University. The body weight of rams was (17.6 ± 1.26 kg). 2.2. Ration: Basal diet was formed from commercial normal diet, containing corn 42%, soybean 16% and bran 42% with adding 0.03%…

equal to the concentration of HC4H4O6-. A scatter plot graph that compares the concentrations of K+ and HC4H4O6- for this part of the experiment is shown in the data below. Another purpose of the experiment is to determine the Ksp value of calcium hydroxide (Ca(OH)2). When Ca(OH)2 is placed in water, it partially dissociates to form Ca2+ and two OH- ions. This is evident in the reaction: Ca(OH)_2 (s)⇄Ca^(2+) (aq)+2OH^- (aq) (3) The Ksp expression for reaction (3) is shown…

Noor Diabi 11AA The life of hydrochloric acid in our stomach Chapter 14 section 1 25/04/2016 Ms. Sara Kassem Sharjah American International School Topic one: Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produced.  Hydrochloric acid (HCl) is a clear, liquid. Which is produced in…

Water Quality Water is essential to human life and the health of the environment. Good water quality is essential for irrigation, drinking and recreation and also sustains ecological processes that support native fish populations, vegetation and bird life. We expect that our water supply will not only be safe, but will taste good, and look crystal clear. Water quality is commonly defined by its physical, chemical, biological and aesthetic (appearance and smell) characteristics. Water quality…
