On dipping a pH paper in a solution , it turns into yellow , then the solution is basic .

On dilution, the pH of a basic solution

A solution turns blue litmus red. The pH of the solution is probably.

A solution turns methyl orange into yellow the approximate pH of solution is

A salt (A) when heated with K_2 Cr_2 O_7 and conc. H_2 SO_4 liberates a gas which is absorbed in NaOH solution. The NaOll solution turns yellow. When this solution is acidified with acetic acid and lead acetate solution is added, a yellow precipitate (B) is formed. (A) is mixed with MnO_2 and heated with conc. H_2 SO_4 when a gas (C) is evolved which tums starch-iodide paper blue. The compound formed, which turns NaOH solution yellow, is:

A solution turns methyl orange into yellow. The approximate pH of solution is : \

A basic solution turns blue litmus red.

Blue litmus paper is dipped in a solution. It remains blue. What is the nature of the solution ? Explain.

Red litmus paper is dipped in a solution. It remains red. What is the nature of the solution? Explain your answer.

When the strip of pH paper was put in a given solution the pH paper changes to orange red. The given solution is most likely to be of:
