1. Vinegar is an acid while lime water (Calcium hydroxide) is a base. Since school we have learnt that acids are sour to taste while bases are bitter to taste.
2.Ammonia is a base while an aqueous solution of Chloride ions gives H+ in aqueous solution and hence acidic
3. Because its a weak acid and give sour and fizzy taste to soft drinks
4. Acidity is defined as a substance which gives H+ in aqueous solution (in water), concentrated sulfuric acid has high concentration of sulfuric acid and doesn't dissociate because water is not present, while dilute sulfuric acid means it is dissolved in water so acid completely dissociates. Hence more acidic
5. Since In HCl H- Cl bond is polar (becoz of huge difference between electronegativities of Hydrogen and Chlorine) so in aqueous solution, this bond breaks to give H+ hence HCl is acidic.. but in CH4 (methane) Bond between Carbon and Hydrogen is not polar (since electronegativities of both Carbon and Hydrogen are nearly same and hence bond is non-polar and it is not broken in aqueous solution, hence its not an acid
6. By defination of strong acids..... since strong acids completely dissociates in aqueous solution... they produce large amount of hydronium ions
7. Sodium bisulphite is formed by reaction of Sodium hydroxide (Strong Base) and Sulphurus acid which is dibasic acid, hence bisulphite ion donates other H+ ions left after reaction with NaOH and hence acidic whille acitic acid is weak monobasic acid
Golden rule-
Strong Base + Weak acid = Basic solution
Strong Acid + Weak Base = Acidic solution
Strong Base + Strong acid = neutral solution
8. Neutral solution which are neither acids nor bases, solution of salts and water give pH of 7..... like solution of table salt NaCl also gives pH of 7
9 There are many reasons. Important one sulphuric acid is strong oxidizing reagent so convert lead(II) to lead(IV) while cooper already being in its highest oxidation state cannot be oxidized further, so react with dil. H2SO4 normally
