Answer 2

When a solution of an acid is mixed with a solution of a base in a test tube (i) The temperature of the solution increases and  (iv) Salt formation takes place (option d).

• When acid and base are combined, salt and water are produced.
• When an acid solution is combined with a base solution in a test tube, neutralisation occurs.
• This process is exothermic, meaning it produces heat and so raises the temperature.
• When acid is given to any base, the temperature of the acid-base reaction rises, making these reactions explosive in nature.
