yes it is dangerous, becasue it will become warmer and then a exothermic reaction will happen
hope this helped ;D
Sulphuric acid should be diluted by adding acid to water while stirring continuously.

This is to dilute the sulphuric acid. Sulphuric acid in high concentrations is dangerous and very corrosive.
A concentrated solution can be weakened by adding more of the solution material (usually water) to dilute it.
Concentrated sulphuric acid and Concentrated Phosporic acid are good dehydrating agents.It removes water from alcohols to convert it into corresponding alkenes.

Dilute sulphuric acid is an aqueous solution, formed by adding water to sulphuric acid, resulting in a homogeneous mixture.
Chemical change
when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.

diluted acid is less concentrated i.e. it is mixed with water and a less harmful(like sulphuric acid.) whereas concentrated acid is in its original form...

Anything you add water to dilutes it.
your ugly
9,8 g concentrated sulphuric acid to 1 L of water (attention to mixing !)
