Which solution is a conjugate acid/base pair with differing spectral absorbencies?
1 Chemical pH indicator
2 Acid/ base buffer
3 Anhydrous solution
4 Hypotonic solution ESupersaturated solution
Explanation:
Chemical pH indicator chemical pH indicator is a conjugate acid/base pair with differing spectral absorbencies. It is used to indicate the endpoint of the titration. For example, phenolphthalein is colourless in acid solution and pink in colour in alkaline solution. Also, litmus is red in acid solution and blue in alkaline solution.
