The equilibrium constant for the solubility equilibrium between an ionic solid and its ions is called solubility constant [1] , Ksp of the solute. For example, the solubility product is defined by MxAy(s) ⇋xM(aq)y++ yA(aq)x- (1) Where M is the metal cation, A is the anion, x and y are …

Pre-Lab 1. If a solid, a gas or a weakly ionizing compound such as H2O formed, then a reaction has occurred. 2. The formation of a solid, the formation of a gas and the formation of a weakly ionizing compound are the driving forces that control a double replacement reaction. …

Vanadium is a very interesting and useful element. It is solid at room temperature and in its pure state it is a grayish silvery metal. It is soft and ductile and it has good corrosion resistance to alkalis, sulphuric acid, hydrochloric acid, and salt waters. Its element symbol is V …

1. Essential and Non-essential Amino acids Amino acids are organic compounds which contain both an amino group and a carboxyl group and may be divided into two groups basing on whether they are produced internally by the human body or not: essential and non-essential amino acids (hyperphysics.phy-astr.gsu.edu, 2012). An essential …

Chemical Weathering is the process of disintegration or decomposition of rocks due to chemical processes. It alters the intrinsic properties such as chemical structure, composition and density of the minerals that the rock is made up of. A rock’s susceptibility to Chemical Weathering depends on the stability of the minerals …

Absorption spectroscopy is a practical way to find what the light absorption of a substance is, and whit this data combining the Beer’s law equation you can determine the concentration of different things in a solution, in this case using a orange Gatorade looking the concentration of its dye which …

Calcium plays a very significant role in our bodies. Approximately 99 percent of the calcium in our bodies is stored in the teeth and bones. Calcium generates about two percent of our total body weight. Calcium is crucial in bone formation, keeping strong bones and teeth and is known for …

Intact protein and base hydrozylate have different color reactions when subjected into various tests. The protein used is Casein which was isolated from milk. Color reactions ,in these test, gives off the information about the composition of a protein. Results often varies from being positive to one and negative to …

The Diels-Alder Reaction is a reaction used in organic chemistry that builds rings very efficiently (1), this cycloaddition process allows for the stereoselective formation of cyclohexene rings possessing as many as four contiguous stereogenic centers (3). This reaction occurs without intermediates, in a single step, which explains the stereospecificity due …

Compounds of boron, notably borax, have been known since early times, but the pure element was first prepared in 1808 by the French chemists Joseph Gay-Lussac and Baron Louis Thénard, and independently by the British chemist Sir Humphry Davy. It is a trace element needed for plant growth, but toxic …
