Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup. Na= 23g/mole Cl= 35g/mole

and adjustment of blood composition involves three processes: glomerular filtration‚ tubular reabsorption‚ and tubular secretion. The first part of the process of urine formation occurs in the glomeruli which act as filters‚ allowing water‚ glucose‚ salt and waste materials to pass through to the Bowman’s capsule but preventing and red blood cells and plasma proteins to pass through. Reabsorption occurs in the proximal tubules of the nephron. Water‚ glucose‚ amino acids‚ sodium and other nutrients

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

Introduction: Making observations are very important in chemistry. It should be done carefully and precisely to ensure no mistakes. This experiment was all about observing. In this experiment‚ a set of chemicals were used to set up an experiment. The experiment was observed for three days. The chemicals used were copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with
