I have one a question about this sentence :

The more acid you add to the solution, the cloudiest it becomes.

I know that is definitely grammatical but really I don't understand. 

Anyone please explain it for me ?The more acid you add to the solution, the cloudiest it becomes.

and 

The more acid you add to the solution, the cloudier it becomes.

Thanks
