Standardization of hydrochloric acid by sodium carbonate Concentrated hydrochloric acid is roughly 11 M. Pour out into a measuring cylinder about 2 cm3 of concentrated hydrochloric acid. Transfer it to a 250 cm3 flask and make up to the mark with water. Shake well. Put some pure sodium hydrogen carbonate or anhydrous sodium carbonate into an evaporating dish and heat gently over a low flame for about fifteen minutes‚ stirring continuously. Take care not to heat the mass too strongly or fusion

E. Reactions of Aldehydes and Ketones with Sodium Hydroxide Objectives: To know the reactions of aldehydes and ketones with sodium hydroxide a) State the function of Sodium Hydroxide in the test. Sodium hydroxide (NaOH) is the oxidizing agent. b) What are the principles involved in the test? What is its purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol

THE DEGREE OF RISK REDUCTION IN DIVERSIFICATION According to Roberts (2004‚ p214)‚ diversification is when several businesses are combined under one ownership for the singular aim of reducing risk. The combination of all the businesses is less risky than individual businesses standing alone. According to Chandler (1959)‚ there are three types of diversification: 1. Full line – company manufacture‚ market and control supplies of its single line of product‚ that is‚ the company has manufacture

Critical Analysis of Literature Review Reduction Technique of Water Evaporation Introduction When water evaporates from water storages it becomes a major issue that affects regions of agriculture in most lands leading to annual loss exceeding potentially to 40 precent and more of water storage. This water which is lost leads to reduction of productivity in agriculture affecting the environment adversely. Literature review has been developed on the same by various researchers

concentrations. Scientific Background: Vinegar is an acid and there fore can be neutralised by an alkali. Acid + Alkali à salt + water Hydrochloric acid + Sodium Hydroxide à Sodium chloride + water Vinegar is a weak acid and therefore it only partially ionises in solution. CH3COOH ßà CH3COO- + H+ An alkali such as Sodium Hydroxide has a formula NaOH. If the alkali is strong then it ionises fully in solution. NaOH ßà Na+ + OH- When the acid H+ reacts with the alkali OH- the

In a solid sample of sodium chloride‚ sodium and chloride are bonded together ionic and so there aren’t any free electrons to support the flow of electricity. When sodium

One of the items contained Sodium Benzoate‚ a small percentage of people are extremely sensitive to sodium benzoate and can experience asthmatic attacks and other allergic reactions when they take in the preservative. A more normal problem is the combination of sodium benzoate and citric acid and ascorbic acid. When these ingredients mix‚ they form benzene‚ a cancer-causing chemical linked with leukemia
