• Rewrite the following statements by adding the correct word as shown in the example: Example: Given Statement: Ammonia changes moist red litmus to blue. Correct Statement: Aqueous ammonia changes moist red litmus to blue. (a) Sulphuric Acid acts as a dehydrating agent. (b) Ammonia reacts with chlorine to give ammonium chloride and nitrogen.  
• write an equation for the reaction of SO² with h²O
  
• draw a draft to show Difference between HCl, HNO3 and H2SO4.
• Why H2SO4 is used in the laboratory preparation of HCl?
• X is formed when SO3 is dissolved in Sulphuric acid.  
• 13. Write the balanced chemical equation to support each of the statements given below (use only dilute sulphuric acid). a. Basic oxide + acid → salt + water b. Metallic carbonate + acid → salt + water + carbon dioxide
• Name the gas evolved when: dil. sulphuric acid reacts with sodium sulphite. Give the balanced chemical equation of the reaction as well.
•  we know water is a non electrolyte since it requires h2so4 to ionize to positively harged hydronium ions and sulphate ions then what property of water makes itself ionize to h+ and oh- ions along with the ionization of the dissolved salts ??  is it so if then why??
