Will sodium sulfide and iron II sulfate form a precipitate? if so what would the reaction look like?
Yes, FeS is insoluble.
Na2S + FeSO4 ==> FeS + Na2SO4

Well, you know what they say, when sodium sulfide meets iron II sulfate, they go out for a fancy dinner at the Precipitation Cafe! And boy, do they make a dramatic entrance with a beautiful reaction!
The reaction can be written as follows:
Na2S (aq) + FeSO4 (aq) → Na2SO4 (aq) + FeS (s)
This reaction involves the exchange of ions, where the sodium from sodium sulfide combines with sulfate from iron II sulfate to form sodium sulfate. Meanwhile, the iron combines with sulfur from sodium sulfide to form iron sulfide, which is a solid (represented by "s").
So yes, my friend, in this scenario, a precipitate (the solid iron sulfide) would indeed form. Just imagine it being the perfect side dish for their romantic dinner!
To determine if a precipitate will form when sodium sulfide reacts with iron (II) sulfate, you need to examine the solubility rules for each compound.
1. Sodium sulfide (Na2S) is a soluble ionic compound. According to the solubility rules, sulfides are generally insoluble, except when paired with Group 1A cations (like sodium).
2. Iron (II) sulfate (FeSO4) is also a soluble ionic compound. Sulfates are generally soluble, except when paired with certain cations, such as Group 2A cations (like calcium), silver (Ag+), or lead (Pb2+).
Based on these solubility rules, both sodium sulfide and iron (II) sulfate are soluble, indicating that they will remain in solution and not form a precipitate when mixed together. Therefore, no precipitate will form in this case.
The balanced equation for the reaction between sodium sulfide and iron (II) sulfate, which does not form a precipitate, would be:
Na2S(aq) + FeSO4(aq) -> Na2SO4(aq) + FeS(aq)
In this reaction, sodium sulfate (Na2SO4) and iron (II) sulfide (FeS) are formed. However, since both products are soluble, they will remain in solution.
To determine if sodium sulfide (Na2S) and iron(II) sulfate (FeSO4) will form a precipitate, we can look at the solubility rules. These rules provide some general guidelines on the solubility of different compounds in water.
Let's begin by examining the solubility of sodium sulfide (Na2S). According to the solubility rules, all sulfides (S2-) are generally insoluble, except when paired with alkali metals or ammonium (NH4+). Sodium (Na+) is an alkali metal, so sodium sulfide is soluble.
Next, let's consider iron(II) sulfate (FeSO4). Most sulfates (SO4^2-) are soluble, with some exceptions like barium sulfate (BaSO4), calcium sulfate (CaSO4), and lead(II) sulfate (PbSO4). Iron(II) sulfate is one of the soluble sulfates.
Based on the solubility rules, both sodium sulfide and iron(II) sulfate are soluble in water, indicating that they will not form a precipitate when mixed.
The reaction between sodium sulfide and iron(II) sulfate would be a double displacement or metathesis reaction. However, in this case, it does not result in a precipitate formation as both compounds remain dissolved in water. The balanced chemical equation for this reaction would be:
Na2S(aq) + FeSO4(aq) → Na2SO4(aq) + FeS(aq)
In this equation, (aq) denotes that the compounds are dissolved in water, indicating their solubility.
