(ii) Name the gases produced during heating. [Hydrated ferrous sulphate, sodium carbonate, carbon, oleum, oil of vitriol, sulphur, glucose, barium chloride, iron (lI) sulphide, hydrogen chloride gas] 1. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind. Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. Iron is treated with steam. [Hydrated ferrous sulphate, sodium carbonate, carbon, oleum, oil of vitriol, sulphur, glucose, barium chloride, iron (lI) sulphide, hydrogen chloride gas] 1. 7H 2 O), traditionally known as "green vitriol" or "copperas", forms beautiful blue-green crystals of the monoclinic system. (c) Write balanced chemical equation for the reaction and name the products formed. So their colour changes from light green to white. Question 17.

Found inside – Page 5Write a balanced chemical equation : FeSO 4 (s) Heat→ Fe 2 O3 (s) + SO2 (g) + ... 2 g of ferrous sulphate crystals are heated in a dry ○ boiling tube. Found inside – Page 53Give chemical equation to show the changes that occur when green coloured ferrous sulphate crystals are heated. Mention the change observed as well as ... ... an aq. (a) State the colour of ferrous sulphate crystal both before heating and after heating. On heating, the colour changes from light green to white. (ii). (a) hydrated ferrous oxide. These fumes are of nitrogen dioxide (NO2 ). When ferrous sulphate crystals are heated their colour changes. On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. The FeSO4 gets oxidized to Fe2(SO4)3 as KMnO4 acts as a good oxidizing agent in an acidic medium. iron (II) sulphate) or ferrous sulfate is the chemical compound with the formula FeSO 4. It is used medically to treat iron deficiency, and also for industrial applications. Note the colour of the ferrous sulphate crystals. (d) Iron nails when left dipped in blue copper sulphate solution become brownish in colour and the blue colour of copper sulphate fades away. Found inside – Page 16(ii) Write the balanced chemical equation for the reaction involved. ... 2 g of ferrous sulphate crystals are heated in a dry boiling tube. Ferrous sulphate crystals (FeS0 4.7H 2 0) lose water when 2g of ferrous sulphate crystals are heated in a boiling tube. Step 1: Small amount of copper sulphate crystals is taken dry boiling test tube. 2 A sulphate of a metal which on distilling produces conc.
