Question

Postlab Questions "Conventional equations are also commonly referred to as molecular equations. In what major way do molecular equations differ from complete ionic or net ionic equations? 1. 2. An inexperienced chemist wants to perform the following reaction in aqueous solution. MgSO4 + 2Nal → Mg, + Na,so, In reality, no reaction occurs when solutions of magnesium sulfate and sodium iodide are mixed. Why? Describe the difference between strong acids and weak acids. How is this difference reflected in the way both kinds of acids are written in ionic equations? Explain your answer 3. 4. Describe, in your own words, what spectator ions are Revised 1/17/17

Answer 1

A molecular equation considers each reactant and product to be neutral compound regarlin of its exact physical state where the net come equation in terns of the ions that are actually reacting. In net ionic equation ions common on lion side of e3quation are cancelled. Eg Neutralization reaction of NaoH & Mcl The molecular eq^n rightarrow NaoH + Hcl rightarrow Nacl + H_2O (l) Net ionic eq^n rightarrow OH^- + H^+ rightarrow H_0 O(l) Mg So_4 + NaI rightarrow Mg I_2 + Na_2 So_4 This reaction does not occur as ions present after mixing the two solution are same as those present in me two solution before mixing without forming a precipitants, gas, complex a any new species. Na is more reactive mass Mh^+2 and NaI is more stable. The difference between strong and weak and is in degree of dissociation. Strong acids ionize completely where as weak acids ionize partially.
