Rank the following acids in order of increasing acid strength when dissolved in water. EXPLAIN your ranking using both inductive effect (think about the O atoms) and the stability of the product (draw all the resonances of the product, think about the number of resonances) HMnO4, H3AsO4, H2SO3, H2SO4
The following pictures represent solutions that contain a weak acid HA (pka = 5.0) and its potassium salt KA. Unshaded spheres represent H atoms and shaded spheres represent A-ions. (K, H30, OH", and solvent H2O molecules have been omitted for clarity.) -HA -A (1) 12) 12) Which of these solutions are buffers? A) (1) and (2) C) (1), (2) and (3) B) (1) and (3) D) All are buffer solutions The following pictures represent solutions at various stages in the...
