more Benedict’s solution (copper sulphate) will be used up. * The precipitate is filtered out then the concentration of the remaining solution can be measured. * This will tell you how much Benedict’s solution has been used up allowing you to estimate the concentration of reducing sugar in the original sample. How Does A Benedict’s Test Work? Benedict’s Solution is a method to determine glucose levels in people suffering from diabetes. It has copper sulphate in it‚ which reacts with sugars

--> Sodium hydroxide + Hydrogen Ans: 2Na (s) + 2H2O (liq) → 2NaOH (aq) + H2 (g). Q.3. Write a balanced chemical equation with state symbols for the following chemical reactions: (i) Solution of barium chloride and sodium sulphate in water to give insoluble barium sulphate and the solution of sodium chloride. Ans:- (i) BaCl2 (aq) + Na2SO4 (aq) →BaSO4 (s) + 2NaCl (aq) (ii) Sodium hydroxide solution (in water) react with hydrochloric acid solution (in water) to produce sodium chloride and water

metal replaces a metal or a non-metal replaces a non-metal. Eg. Magnesium + zinc sulphate = magnesium sulphate + zinc Double displacement is the swapping of elements‚ usually forming a solid. Eg. Lead nitrate + sodium chloride = sodium nitrate + lead chloride Neutralization is the reaction between an acid and alkali/base/carbonate . One example of neutralization is Sulphuric acid + magnesium oxide = magnesium sulphate + water Sodium hydroxide is a corrosive metallic base‚ and it is also called

Topic 11a – Group 7‚ the Halogens Revision Notes 1) Trends in physical properties of the elements • At room temperature‚ Cl2 is a pale green gas‚ Br2 is a brown liquid‚ I2 is a blue-black solid. • In Group 7‚ boiling point increases down the group because the molecules have more electrons and‚ therefore‚ stronger van der Waal’s forces which require more energy to overcome them • Electronegativity is the ability of an atom to attract the electrons in a covalent bond • Down

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are
