Question

Effects of changes in concentration
A. Equilibrium of the aqueous ion Cu2+ it’s balance quimica equation is: The color of CuSO4 is Light Blue when you add NH3 turns Dark Blue
when you add HCl Light Blue 1. the balance shifted by adding NH3? explain
2. the balance shifted by adding HCl? explain

B. Equilibrium of the aqueous ion Ni2+ it’s balance chemical equation is The color of the solution NiCl2 is Light Green When added NH3 turns blue When added HCl turns Light Green 1. the balance shifted by adding NH3? explain
2. the balance shifted by adding HCl? explain 1. the balance shifted by adding NH3? explain
2. the balance shifted by adding HCl? explain
C. The Aqueous Equikibrium of Co(H2O)6^2+ and CoCl4^2- It’s balance chemical equation is The color of the system at room Tempe tire is Light Purple When added AgNO3 (ac) it turns Pink When added NH4Cl (s) it turns Blue 1. the balance shifted by adding AgNO3(ac)? explain
2. the balance shifted by adding NH4Cl(s)? explain 1. the balance shifted by adding AgNO3(ac)? explain
2. the balance shifted by adding NH4Cl(s)? explain 4 (ac

Explanation / Answer

A.

1. Right side . Because added NH3 increase the concentration of NH3 at reactants side

2. Left side. Because Added HCl reacts with NH3 to convert it into NH4Cl and decrase the concentration of NH3

B.

1. Right side . Because added NH3 increase the concentration of NH3 at reactants side

2. Left side . Because Added HCl reacts with NH3 to convert it into NH4Cl and decrase the concentration of NH3

C.

1. Left side. Because added AgNO3 removes Cl- in the form of AgCl

2. Right side. Added NH4cl increases the concentration of Cl-

NOTE:

Increase in concentration of reactants shifts the equilibrium towards rigth side and increase in concentration of products shift the equilibrium towards left side.
