2CrO42-(aq, yellow) + 2 H3O+(aq) = Cr2O72-(aq, orange) + 3H2O(l)
The equilibrium mixture is yellow in color.
What direction will the equilibrium shift and what color should the mixture be after adding
Na2CrO4(s) to the equilibrium mixture?
right; more orange - CORRECT ANSWER-A student is studying the equilibrium represented by
the equation:
2CrO42-(aq, yellow) + 2 H3O+(aq) = Cr2O72-(aq, orange) + 3H2O(l)
The equilibrium mixture is yellow in color.
, What direction will the equilibrium shift and what color should the mixture be after adding
concentrated HCl to the equilibrium mixture?
shift right; more yellow - CORRECT ANSWER-HX(aq) = H+(aq) + X-(aq)
Suppose HX(aq) is red and X- is yellow. How would an equilibrium mixture behave if we were to
add KOH(aq)?
shift right; more yellow - CORRECT ANSWER-HX(aq) = H+(aq) + X-(aq)
Suppose HX(aq) is red and X- is yellow. How would an equilibrium mixture behave if we were to
add NaOH(aq)?
shift left; more red - CORRECT ANSWER-HX(aq) = H+(aq) + X-(aq)
Suppose HX(aq) is red and X- is yellow. How would an equilibrium mixture behave if we were to
add concentrated HCl?
shift left; more red - CORRECT ANSWER-HX(aq) = H+(aq) + X-(aq)
Suppose HX(aq) is red and X- is yellow. How would an equilibrium mixture behave if we were to
add concentrated H2SO4?
H2O, OH- - CORRECT ANSWER-What is an example of a (conjugate acid, conjugate base) pair?
Zn(NO3)2 - CORRECT ANSWER-What salt yields an acidic solution in water?
KBr - CORRECT ANSWER-What salt yields a neutral solution in water?
