Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

pain control and patient mobility. As a standardization practice‚ the new protocol decreased the time spent on decision-making and the number of suppliers. However‚ one of the issues with this change is resistance from surgeons who used different prostheses. While most surgeons followed the protocol‚ the hospital needs to know how to motivate doctors to use the same prostheses as it can boost the hospital’s bargaining power with suppliers. Why Standardization Would Reduce Costs and Improve Quality

BTEC Chemistry – Titration experiment I – Standard Solution Prep Preparation of a standard solution of sodium carbonate Anhydrous sodium carbonate is a suitable chemical (primary standard) for the preparation of a standard solution. Standard Solutions are critical in chemistry because you need to have solutions with an EXACT known concentration and volume. Chemicals/Materials: solid sodium carbonate (Na2CO3) distilled water Apparatus: 250cm3 volumetric flask 250cm3 beaker Glass
