Different antacids 8. Side effects 9. Nursing implifications 10. Inference Abstract of the work under taken Antacids are medicines that neutralize stomach acid. They are used to relieve acid indigestion‚ upset stomach‚ sour stomach‚ and heartburn. Antacids are taken by mouth and work by neutralizing excess stomach acid. They contain ingredients such as aluminum hydroxide‚ calcium carbonate‚ magnesium hydroxide‚ and sodium bicarbonate‚ alone or in various combinations. Antacid products

Recrystallization of Benzoic acid Chemistry 204-002 Date: 4/9/2011 Hector Ortega Recrystallization is a method used to purify compounds‚ and this is a very important procedure because compounds are naturally impure. Polarity and solubility play a big role in this experiment and these characteristics are exploited in order to have a crystallization of the desired compound. In this experimented benzoic acid was crystallize using ethanol and water. I chose these solvents based on part C of the experiment

Marisol Cardenas-Rios March 9‚ 2015 Jim Roufus Intrathecal Injection Preparation General Purpose: To demonstrate a sterile preparation process. Specific Purpose: To demonstrate to my audience how to prepare an intrathecal injection. Central Idea: The importance to utilize appropriate aseptic technique to ensure that the intrathecal injection being prepared is sterile. Introduction: I. My favorite sterile preparation is the intrathecal injections‚ also known as “pain pumps” that are used for

Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

Experiment Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pH balanced and neutral? Information Gathered pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid has a sour taste‚ hence‚ will react to metal and will be corrosive; therefore‚ they are considered as an electrolyte

to practice common organic laboratory techniques inside the lab to get one oriented to the basic methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form‚ consisting of benzoic acid‚ methyl orange‚ a common acid/base indicator‚ and cellulose‚ a natural polymer of glucose (Huston‚ and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating

Electrophoresis of Amino Acids Introduction: Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field. This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino acids‚ in solution‚ to act as charged polyelectrolytes that can migrate in an electric field. The amino acids with a net positive charge will migrate toward

Drills And Preparation for Emergencies An act of terrorism carried out by the group‚ Al Qaeda‚ destroyed the lives of thousands of people. Although disasters such as the one that occurred on September 11‚ 2001 cannot necessarily be prevented‚ people can prepare for them as they would any other emergencies. Drills and practice are the most important aspects of emergency preparedness and are crucial for survival in disaster situations. In the book‚ 102 Minutes‚ by Kevin Flynn and Jim Dwyer‚ stories

9.1 Sulphuric Acid Sulphuric Acid is Manufactured in Industry 1. Sulphuric acid‚ H2SO4 is manufactured in industry through Contact Process. 2. The raw materials used are sulphur‚ air and water 3. The Contact process consists of three stages. Stage 1: The production of sulphur dioxide This can be obtained by two methods: 1. Burning of sulphur in dry air in the furnace S + O SO2 2. Burning of metal sulphide such as zinc sulphide or iron(III) sulphide in dry air. 2ZnS
