M = 0.0101 mol NaOH/ 0.048 L To tell if K3PO4 (Potassium phosphate) forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization reaction that formed K3PO4 .First we need to figure out the acid and base that were neutralized to form Potassium phosphate. For example, if your substance dissolved in 500 mL of water, 0.0021 moles per liter 0.5 liters = 0.00105 moles. Match each type of compound with the ion each produces. 2 Al3+ (aq) + 6 H+ (aq) + 6 Br- (aq) --> 2 Al3+ (aq) + 3 H2 (g) + 6 Br - (aq) To show that they are dissolved in water we can write (aq) after each.

What remains when the spectator ions are removed is called the net ionic equation, which represents the actual chemical change occurring between the ionic compounds: It is important to reiterate that the spectator ions are still present in solution, but they do not experience any net chemical change, so they are not written in a net ionic equation. At the same time, the K2SO4 is a very different substance than K+ and SO4 2-.If you need to know how to balance chemical reactions, see my complete tutorial on balancing all types of chemical equations:Balancing Equations in 5 Easy Steps: https://youtu.be/zmdxMlb88FsMore Practice Balancing: https://youtu.be/Qci7hiBy7EQDrawing/writing done in InkScape.
