Any idea what's happened here or how best to deal with the leakage? It is better to dissolve Phosphorous Acid first and then dissolve potassium hydroxide. Therefore, the final is: Overall reaction, H3PO4(aq) + 3K+(aq) + 3OH-(aq) => 3H2O(l) + 3K+(aq) + PO4-3(aq), Since 3K+ is on both sides, the net ionic equation is e), H3PO4(aq) + 3OH-(aq) =>3H2O(l) + PO4-3(aq). c) H3PO4(aq) + 3KOH(aq) ® K3PO4(aq) + 3H2O(l), d) 3H+(aq) + 3KOH(aq) ® 3K+(aq) + 3H2O(l), Please explain how you got the answer thankyou. Look at the link below for more info on "net ionic equations". PO4^3- will react with water to make HPO4^2-, and even some H2PO4^-.

Use It Earlier to Protect Crops In Advance and Reduce Disease After dissolving in water, Phosphorous Acid becomes phosphoric acid easily and it will reduce the effect, so please use it up on that day. Since there are potassium and phosphate ions on both sides of the equation, they cancel out. So in reality there will be a number of species in solution, and the concentration of each will depend on the pH of the solution: H+, OH-, PO4^3-, HPO4^2-, H2PO4^-, H3PO4, and K+. Recommended By Taiwan Agricultural Research Institute, All kinds of fish and shrimp fry/fingerling. So about a year ago I purchased a bottle of Ph Up and a bottle of Ph Down for my gardening needs.
