WebA solution of 4-nitrophenol appears colorless below pH 5.4 and yellow above pH 7.5. This color-changing property makes this compound useful as a pH indicator . The yellow color of the 4-nitrophenolate form (or 4-nitro phenoxide ) is due to a maximum of absorbance at 405 nm (ε = 18.3 to 18.4 mM −1 cm −1 in strong alkali). [4] WebWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid …
WebA solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
