In aqueous solution, it is only a few percent ionized. Which of the following ionic compounds is . In contrast, equations that show only the hydrated species focus our attention on the chemistry that is taking place and allow us to see similarities between reactions that might not otherwise be apparent. Problem #22: ammonium phosphate + calcium chloride --->. That forces the dihydrogen phosphate into the base role, that it, to accept a proton. Another possible problem is that the copper(II) hydroxide will be treated as soluble and written as the ions rather than the solid. Don't try and argue the point. 6OH-(aq) + 3H2PO4- ---> 3PO43-(aq) + 6H2O(). We will discuss solubilities in more detail later, where you will learn that very small amounts of the constituent ions remain in solution even after precipitation of an insoluble salt. We will: balance K atoms by multiplying CHCOOK by 2. However, in reality, sulfuric acid is strongly ionized in its first hydrogen and then not strongly ionized in its second hydrogen. Now, what I can do when I write my net ionic equation is I basically eliminate those spectator ions. Comment: thallium compounds are not commonly asked in these types of questions nor are thallium compounds commonly included in a solubility table. Here's an NR asked in a good way: If solutions of Co(NO3)3 and Mg(ClO3)2 are mixed, how many precipitation reactions will occur? This is what should be done: Notice that it is liquid water and gaseous carbon dioxide. If you treat the above as a double replacement reaction, you can see that the sodium ion and the chloride ion are the spectator ions. 3KI(aq) + (NH4)3PO4(aq) ---> K3PO4(aq) + 3NH4I(aq), Problem #24: Write the molecular and net ionic equations for: TlNO3(aq) + KI(aq) --->.
