WebApr 10, 2024 · A pH of 12.4 indicates a pOH of 14-12.4 = 1.6. As pOH = -log [OH - ], the [OH -] is the antilog of - 1.6 = 0.0251 M/L. The number of grams of OH - required would be 0.0251 moles / L x 17.0 g/mole x 1L/1000 mL x 500 mL = 0.213 g OH -. The mass of KOH needed then is molar mass KOH / molar mass OH - x g OH -. WebSep 11, 2024 · Respiratory burst oxidase homologs (Rbohs) play a predominant role in reactive oxygen species (ROS) production, which is crucial in plant growth, differentiation, as well as their responses to biotic and abiotic stresses.

WebJul 24, 2016 · pH = 13.30. Explanation: Barium hydroxide is a strong base for both stages of dissociation: Ba(OH)2(s) → Ba2+ +2OH− So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: [H+][OH−] = 1.0 ×10−14M [OH−] = 2.0 × 10−1M [H+] = 5.0 ×10−14M And then pH = −log10([H+] = 5.0 × 10−14) = 13.30. Answer link Web– rubidium hydroxide RbOH – cesium hydroxide CsOH A 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.
