Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the analyte. The molarity of the sodium hydroxide was found

Experiment 1 : Redox Titration Using Sodium Thiosulphate Abstract This experiment is to determine the concentration of oxidizing solution using the iodine/ thiosulphate titration where the reducing solution is potassium iodate solution and the oxidizing solution is sodium thiosulphate solution. Potassium iodate solution which is an oxidizing agent is added into an excess solution of acidified potassium iodide. This reaction will release iodine. Potassium iodide is acidified with sulphuric acid

“What are the effects of specific gravity‚ urine output volume‚ and salt concentration when you ingest a hypertonic‚ hypotonic‚ and isotonic solution?” Specific Gravity: Is the ratio of the density of a substance to the density (mass of the same unit volume) of a reference substance. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. Urine specific gravity results fall between 1.002 and 1.030 if your kidneys

Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium pump. Thirdly‚ the molecular basis of the Action Potential will be explained including a description of hyper polarisation‚ depolarisation and the purpose of the refractory period. Fourthly‚ a description of how a signal moves through

When a basic solution like sodium hydroxide is added To a cloth strip treated with onions then the smell cannot be detected‚ however an acidic solution does not destroy the smell of onion. Vanilla extract has a characteristic pleasant smell. If a basic solution like sodium hydroxide is added to it we cannot detect the characteristic smell of vanilla extract

EXPERIMENT 2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain

Questions to be submitted as Case Study 1 1) Define Hyponatremia.- When sodium concentration in the blood is below 135 mEq/L‚ or abnormally low. It is induced by the consumption of large amounts of fluid that are sodium-free‚ such as water. 2) What is the etiology of hyponatremia?- Can occur in three ways: hypervolemic‚ euvolemic‚ and hypovolemic. Hypervolemic is when the body overall has too much water‚ lowering the serum sodium level‚ thus causing cells to swell. Euvolemic is when the body’s water

Solid sodium carbonate 18. Distilled water Theory: To determine the exact concentration of a monobasic acid‚ HX‚a standard base solution is prepared. Then‚ a certain amount of standard base solution is titrated with the monobasic acid. This is an acid-base titration. The equation for the reaction is Na2CO3(aq) + 2HX(aq) → 2NaX(aq) + H2O(l) + CO2(g) Procedure: 1. Weight accurately about 13.20-13.50g of solid sodium carbonate in a small beaker
