Solution

1 ml of concentrated sulphuric acid is diluted to 100 times means its normality is made to 100 times of its original concentration 36 NV1N1 = V2N21 × 36 = V2 × 36100V2 = 100 mlThat is on adding 100 -1 = 99 ml water, the solution becomes 100 times diluted.Always when you are diluting a solution, acid should be added to water.Not water to acid, which may cause so much of heat to get released and the acid may splash..
As per the volumetric principle
