Question

solid sodium bicarbonate was placed on the strip of pH paper . What would be the colour of pH paper and why?​

Answer 1

Answer:

The colour of the pH paper did not change because pH paper shows colour depending on the hydrogen ion concentration in solution. Solid sodium bicarbonate does not produce hydrogen ions in its solid state thus does not give any colour on pH paper.

Answer 2

Explanation:

No colour change. Sodium bicarbonate is in solid form. Ions dissociates in aqueous solution only.
