Is methanol (CH3OH) a strong electrolyte, a weak electrolyte, or a non-electrolyte when dissolved in water? A concentration cell is constructed at 25 C based on the Zn/Zn2+ electrode. The concentration of Zn2+ is known to be 1.3 M at the positive electrode. If the ...
Strong acids completely dissociate in water to produce a hydronium ion and a very weak base. Weak acids only partially dissociate in water, so they only form a small percentage of hydronium ions and a weak base. Vinegar is a good example of a weak acid. Answer and Explanation: H...
Until recently, the coupling between OH and CH3OO had not been investigated, despite the large rate coefficient recommended by Tsang and Hampson12 (k = 1 × 10-10 cm3 s-1) and the suggestion that a major product would be methanol (CH3OH)13. Four likely product channels exis...
Base Dissociation Constant of a Conjugate Base: The acidity of a weak acid is described by the acid dissociation constant Ka. Weak acids also produce their conjugate base upon hydrolysis in water. This base will have a base dissociation constant Kb. The Ka of the acid and the Kb of the ...
A weak acid has a K_a = 3.8 times 10^-9. What is pK_a for this acid? When an acid reacts with a base, what is the type of reaction called? Which of the following are acids? a) CH4 b) HCl c) CH3OH d) H2SO4 e) HCl and H2SO4 ...
Let's assume HA is a weak acid. HA(aq)+H2O(l)→A−(aq)+H3O+(aq) ka=[A−][H3O+][HA] HereA−(aq) is a conjugate base of acid the acid HA. Base dissociation reaction. A−(aq)+H2O(l)→HA(aq)+OH−(aq) kb=[HA][OH−][A−] ...
Classify C12H22O11 as a strong electrolyte, a weak electrolyte, or a non-electrolyte. Identify if the given compound acts as a strong electrolyte, weak electrolyte, or non-electrolyte. Write an equation that shows the dissociation of the strong electrolyte. CH3OH ...
What is the conjugate base for H2PO4-? Which of the following is not an acid-base conjugate pair? (a) H2S and OH- (b) H2CO3 and HCO3- (c) NH4+ and NH3 (d) H2O and OH- (e) none of the options 1. What is the conjugate base of HCO_3^-? Express your answer as a chemic...
