The following soluble salts are strong electrolytes. For each, write a balanced equation for their dissociation in water.
NaBr
BaBr2
Li3PO4
What's the problem here.
NaBr ==> Na^+ + Br^-
Li3PO4 ==> 3Li^+ + PO4^3-
To write the balanced equation for the dissociation of a soluble salt in water, we need to identify the ions that it dissociates into. The ions are obtained by breaking down the chemical formula of the salt.
1. NaBr:
The chemical formula of sodium bromide is NaBr. When it dissolves in water, it dissociates into sodium cations (Na+) and bromide anions (Br-). The balanced equation for the dissociation is:
NaBr (s) -> Na+ (aq) + Br- (aq)
2. BaBr2:
The chemical formula of barium bromide is BaBr2. When it dissolves in water, it dissociates into barium cations (Ba2+) and bromide anions (Br-). The balanced equation for the dissociation is:
BaBr2 (s) -> Ba2+ (aq) + 2Br- (aq)
3. Li3PO4:
The chemical formula of lithium phosphate is Li3PO4. When it dissolves in water, it dissociates into lithium cations (Li+) and phosphate anions (PO43-). The balanced equation for the dissociation is:
Li3PO4 (s) -> 3Li+ (aq) + PO43- (aq)
These are the balanced equations for the dissociation of NaBr, BaBr2, and Li3PO4 in water.
