The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Formal Lab Report Analysis of Antacid Tablets I. Introduction An acid-base titration is a method of neutralizing strong acids. Unbeknownst to many‚ acid-base titrations occur on a daily basis. Our stomachs use acid to help us digest our food – approximately .155 hydrochloric acid (HCl) with a pH of 2-3. When too much of this acid is formed in the stomach‚ heartburn and other discomfort occurs. This is when people grab for their antacids; these are bases that neutralize the

about the how‚ why‚ and the belief system to get a better understanding of what offenders are thinking. There have been many critics of rational choice theory in relation to neutralizations; however‚ neutralizations are strategies that are typically used by criminals to justify their actions. There has been five main neutralization techniques that I believe truly give us a better look into an offenders thoughts and decision in regards to crime (Maruna & Copes‚ 2005). First‚ to mention the five techniques

Enthalpy of Neutralization Introduction Energy changes always accompany chemical reactions. If energy‚ in the form of heat‚ is liberated the reaction is exothermic and if energy is absorbed the reaction is endothermic. Thermochemistry is concerned with the measurement of the amount of heat evolved or absorbed. The heat (or enthalpy) of neutralization (∆H) is the heat evolved when an acid and a base react to form a salt plus water. Eq. 1 HNO2(aq) + NAOH(aq) → NaNO2(aq) + H2O(l) + Q Q in the

Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

Heat of Neutralization: Lab Report In part A of this lab I determined the heat capacity of a calorimeter made out of two Styrofoam cups nesting together with a cardboard top containing a hole in the middle. First I placed 50 mL of water in the calorimeter‚ waited five minutes for the water to reach equilibrium‚ and used the computer’s temperature instrument to record the final temperature of the system. Next I heated 50 mL of water in a 250 mL beaker until the water reached 43.1 C (approximately

Gender neutralization. Is the premise outlined in “X” and currently happening to Storm wrong or right? There are a lot of problems arouse on the issue of Gender neutralization. People start commenting about it‚ they blog‚ post videos on Youtube etc. They all answered the question if gender neutralization is either right or wrong and if it’s appropriate to early new bourns?

Skyes and Matza’s theory on the techniques of neutralization was originally channeled towards juvenile delinquency but is also very effective for understanding how police officers excuse‚ justify‚ and rationalize unethical behaviors. Techniques of neutralization are used to maintain a positive self-image: denial of responsibility‚ denial of injury‚ denial of the victim‚ condemnation of condemners‚ and appeals to higher loyalties. Denial of responsibility provides police with a justification for
