1. Is Sodium hydrogen carbonate(NaHCO3) a basic salt or an acidic salt? According to defn, since it has a hydrogen atom, it should be acidic, but in reality, NaHCO3(Baking soda) is used to neutralize acids right? 2. Do basic soluions too have H+(aq.) ions? Explain why they are basic by taking an example. 3. Why is "Contact" Process called so? I was just curious. 4. Why is Ammonium "Chloride" used in Lab. Prep. of Ammonia? 5. Are Deliquescence, Efflorescence, etc. in syllabus? They aren't mentioned... 6. Why is it "Basicity of Acids" and "Acidity of Bases" ? Why not "Basicity of Bases" and "Acidity of Acids" ?(Again, curiosity) 7. Colour changes in which indicators should we remember ? Is Litmus, Methyl Orange & Phenolphthalein enough? 8. Syllabus of Metallurgy starts from Minerals and Ores, right? I assume general properties of metals and non-metals aren't in syllabus? 9. Is Na2CO3 a basic salt, or a normal salt? Since it's made of a strong base & weak acid, but at the same time, doesn't have OH- ions to make it basic... 10. Are numericals on pH value required? Sorry if it's a bit too long(I know it is). But I'd appreciate anyone taking out time to answer these. |
