Determination of the Solubility Product Constant of Calcium Hydroxide Introduction 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 the corresponding charges of the ions. The equilibrium expression is Ksp=[MY+]x[AX-]Y (2)

LACTOSE – C12H22O11 Chemical and Biochemical Properties Lactose is very stable and inert from a chemical point of view. It has no significant tendency to react with the drug or other components of a formulation. Some remarks on the chemical properties of lactose are useful however‚ the low hygroscopicity of crystalline lactose supports its virtual chemical inertness. Most chemical reactions of lactose occur noticeably only in aqueous environment. Because lactose has a very low tendency to attract

unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and will not work. Materials/Methods

Lactase is an enzyme that splits up the disaccharide lactose into monosaccharides glucose and galactose‚ but its function diminishes with age resulting in a wide use of lactase supplements. This enzyme functions under specific conditions‚ so we investigated the effect different salt concentrations have on the enzyme activity. Serial dilutions were performed to prepare a lactase solution as well as twenty percent‚ fifteen percent‚ and five percent concentrations of NaCl. Three different treatments

(lactase) to a specific substrate (lactose). Students will observe the actions of the enzyme and how shape is important to enzyme reactions. Background information: Lactose‚ the sugar found in milk‚ is a disaccharide composed of glucose and galactose (both six-sided sugars). Sucrose‚ ordinary table sugar‚ is also a disaccharide composed of fructose and glucose. Glucose is a six-sided sugar and fructose is a five-sided sugar. Lactase is an enzyme that breaks lactose down into galactose and glucose

Soap is formed by molecules with a "head" which likes water (hydrophilic) and a long chain which hates it (hydrophobic). 7. Lactose is the main complex sugar found in the milk. It’s a pretty big compound formed by two smaller components: glucose and galactose. Such a big compound cannot get through the intestinal wall and into the bloodstream‚ so we need "something" to break it

Abstract Lactose Intolerance is a condition that effects people who do not produce enough lactase to digest lactose. There are three different types of Lactose Intolerance that are caused by the small intestine and the amount of lactase produced. Lactose Intolerance effects those who have the condition by causing pain and making them uncomfortable ("Lactose intolerance"). Lactose Intolerance Introduction Lactose Intolerance is a condition that effects one out of every ten Americans
