People Also Ask about
What happens if there is no precipitate?
If there is no precipitate, then there is nothing to drive the reaction. Both possible products would be soluble, and so there is no net reaction (it's just the reactant ions in solution).
Are precipitates included in net ionic equation?
Step 3: Think about your result. For a precipitation reaction, the net ionic equation always shows the two ions that come together to form the precipitate. The equation is balanced by mass and charge.
Is there a net ionic equation if there is no precipitate?
For reactions in this activity that do not produce a precipitate, all ions remain in the aqueous state. No molecular compounds are formed either. Consequently, all ions get canceled and there is no net ionic equation that can be written. No net ionic equation possible.
What is the net charge of a precipitate?
The net charge of a precipitate formed when two solutions containing ionic substances are mixed is zero. This is because the precipitate is an ionic compound composed of cations and anions, and the overall charge must be neutral, with the positive charges of cations balancing out the negative charges of anions.
How to write net ionic equation if there is no precipitate?
For reactions in this activity that do not produce a precipitate, all ions remain in the aqueous state. No molecular compounds are formed either. Consequently, all ions get canceled and there is no net ionic equation that can be written. No net ionic equation possible.
What is the term for the ions that do not precipitate?
These are called spectator ions because they remain unchanged throughout the reaction. Since they go through the equation unchanged, they can be eliminated to show the net ionic equation: C+ (aq)+ B- (aq) → CB (s) The net ionic equation only shows the precipitation reaction.
What is the ionic equation for precipitation reaction?
AX + BY → AY + BX, where A, B, X and Y are all ions. An ionic solution is when the ions of a compound have dissociated in an aqueous solution. A reaction happens when you mix two aqueous solutions. This is when you find out if a precipitate will form or not.
