How do you lower the pH of a solution with a pH of 10?

Question

i need to lower the pH of my solution to 4.5 but the pH is 10...how would i lower it

Answer 1

DILUTE IT WITH WATER
DROP BY DROP

THE PH WILL DROP

IF YOU ADD AN ACID ,A REACTION TAKES PLACE AND THE PH WILL SETTLE AT 7 ,NOT 4

Answer 2

A pH of 10 is a fairly strong alkaline, so when it is alkaline, add an acid, such as hydrochloric acid (otherwise a weak household acid), add this drop by drop. For the solution to have a pH of 4.5, the acid content needs to be higher than the alkaline. After you have done this, check using universal indicator or something similar.
Doesn't take a minute

Answer 3

D would have the highest base and the highest pH because there are two OH- Ions. Nitric Acid is a very strong corrosive acid and would have the lowest pH Answer would be A lowest, D highest.

Answer 4

You want your final solution to have a pH < 7, so you must add an acid. A weak acid, like ethanoic acid in vinegar, will do the job. Acid must be in excess in the final solution so that pH < 7.

Answer 5

Add some acid ( e.g sulphuric acid) This will lower the ph value

Answer 6

Add water makes it's own sauce. Actually, beer or vinegar might work.

Answer 7

put an acid in it

Answer 8

and if it is base type solution pour acid type solution
