ICSE Class 10 Chemistry Properties of Acids and Bases

• State the term -  The number of hydrogen ions with which a molecule of that base will react to produce salt and water only.
• why acids produces h+ion
• A water molecule has 2 lone pair of electrons ,with one pair proton combines and make H30+ ,so is there a chance of H4O+ when another proton combines with H3O+?
• what happens when iron reacts with potassium nitrate and concentrated hcl  
• lead oxide is a metallic oxide which reacts with hydrochloric acid to produce dash
• What is The basicity  of hydrogen in acetic acid ?
• Why nitric acid cannot be concentrated beyond 68% by the distillation of a dilute solution of HNO3?
• why concentrated sulphuric acid is always added to water and not the water to concentrated sulphuric acid ? why the mixture gets hot?
• it is said that we should never add water to acid but then what should be done to make the acid dilute?
• ammonia is basic gas and when it reacts with sulphuric acid which is acidic in nature it produces Ammonium sulphate , but this reaction is not an example of neutralization reaction (it does not produces acid and base)?
