Dilute solutions of Fe(NCS)2+ have their equilibrium positions shifted with the addition of Fe(NO3)3, KSCN, NaOH, and AgNO3. The ferric thiocyanate solution is blood red in color, and the intensity of ...

The acid and conjugate base each have different colors and as the equilibrium shifts from one direction to the other, the color of the indicator changes. As an example, the equilibrium of a weak acid ...

This is called an equilibrium and is present in water and ... Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the ...
