    5 mol Total KOH required = 10 + 2.5 = 12.5 mol. Question 2 Two acids H2SO4 and H3PO4 are neutralized separately by the same amount of an alkali when sulphate and dihydrogen orthophosphate are formed respectively. Find the ratio of masses of H2SO4 and H3PO4 [at mass P = 31] Ans. H2SO4 + 2NaOH Na 2SO4 + 2H2O H3PO4 + NaOH NaH2PO4 + H2O Equivalent of alkali = 1 g equivalent of H2SO4 = 1 g equivalent

    To calculate the enthalpy change of neutralization of the given pairs of acid and base. Theory: When alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions‚ H+(aq) from the acid react with the hydroxide ions‚ OH-(aq) from the alkali‚ forming water. Ionic equation: H+ (aq)+OH- (aq) → H2O (l) The identity of the salt will depend on the nature of the acid and alkali used. The combination of H+ and OH- ions in this way releases energy. In this practical‚ the enthalpy changes

    Introduction Metallic yarns or threads‚ in general‚ have been known for more than 3000 years. Gold and silver were hammered into extremely thin sheets‚ then cut into ribbons and worked into fabrics. These were the first ‘man made’ fibres‚ which came thousands of years before nylon or rayon. The Persians made fabulous carpets with gold thread and the Indians‚ ornamental sarees with it. The metal threads were twisted‚ doubled or wrapped around some other thread such as cotton. With the advancement

    Discussion The main purpose of this lab was to synthesize four soaps and two detergents and determine which one would be the best for an environmental group to use in the event of an oil spill.1 To complete this task‚ five subgoals had to be achieved first. To find the solubility of the fats‚ oils‚ soaps‚ and detergents‚ each of them were placed into different solvents to see if they dissolved. None of the oils and fats were soluble in water (H2O)‚ sodium hydroxide (NaOH)‚ or hydrochloric acid

    DESCRIBE THE PROPERTIES OF ( FINE AND COARSE ) AGGREGATES ? REPORT Aggregates are defined as a combination of distinct parts gathered into a mass or a whole. They can increase stability of a structure and protect it from bad weather. In addition‚ aggregates can also increase quality and reduce price of the cements beacause of their greater volume stability and filling function. Therefore‚ it is important for civil engineers to understand properties of aggregates. Aggregates’ properties are the
