Question
Identify the conjugate acid-base pairs in the equation (a): H_2SO_4(aq) + H_2PO_4^- (aq) HSO_4^- (aq) + H_3PO_4(aq) H_2SO_4/HSO_4^- and H_2PO_4^-/H_3PO_4 H_2SO_4/HSO_4^- and H_3PO_4/H_2PO4^- HSO_4^-/H_2SO_4 and H_2PO_4^-/H_3PO_4 HSO_4^-/H_2SO_4and H_3PO_4/H_2PO_4^- Identify whether the equilibrium mixture in the equation above contains mostly products or mostly reactants. The equilibrium contains mostly products The equilibrium mixture contains mostly reactants Identify the conjugate acid-base pars n the equation (b); HCO_3^-(aq) + H_2O(l) H_3O^+ (aq) + CO^2-_3 (aq) CO^2_3/HCO_3^- and H_3O^+/H_2O HCO_3^-/CO^2-_3 and H_3O^+ H_2O HCO_3^-CO^2-_3 and h_2O/H_3O^+ CO^2-_3/HCO_3^- and H_2O/H_3O^+Explanation / Answer
A)
H2SO4 is acid and HSO4- is its conjugate base
H2PO4- is base and H3PO4 is its conjugate acid
Answer: H2SO4/HSO4- and H2PO4-/H3PO4
option 1
B)
Since H2SO4 is strong acid, H2SO4 will be reacting completely
Hence the equilibrium mixture contains mostly product
C)
This is similar to part A
HCO3- is acid and CO32- is its conjugate base
H2O is base and H3O+ is its conjugate acid
Answer:
HCO3-/CO32- and H2O/H3O+
option 3
