Sure the liquid is acidic B is certainly correct but you can not say if it is a weak acid or a strong acid at a very low concentration

the liquid is definately acidic in nature.but it cannot be said that it is a weak or strong acid as pH is a function of conc.also it can be a salt solution of some strong acid weak base as they also due to salt hydrolysis are acidic.the substance may also be hazardous.

It is an acid...
Probably a weak 1... because ... less pH means strong acid.
And the usual pH limit for acid is.. 0-6.9999999
As pH 7 is for the nutral solution

d. because the ph is 4. if it was 2 or 1 it would be strong.

It relies upon on what area of the recommendations you attempt to maintain sharp. For me, i'm analytical by using nature, so I take excitement in staying sharp by using doing cryptograms, or analyzing the racing type(horse racing). quite often, puzzles of any type are an dazzling way of sprucing your recommendations. in simple terms decide for the section(s) you desire to sharpen, and discover the puzzle the fits your guy or woman want(s).
