- The N a ion has a +1 charge and the SO4 ion has a −2 charge. In order to give balance, we must have two Na ions to give an overall +2 with regards to Na: this, thus, neutralises the compound. Therefore, the formula is: N a2SO4

Mar 11, 2022 · What is the formula for the ionic that forms when the lead(IV) (\(\ce{Pb^{4+}}\)) ion reacts with the sulfate (\(\ce{SO4^{2-}}\)) ion? Answer. Add \(\ce{Pb(SO4)2}\). \(\ce{Pb^{4+}}\) and \(\ce{SO4^{2-}}\). For every one Lead(IV) ion, you need two sulfate ions to be charge neutral. 1(+4) + 2(-2)=0.

As a diligent student of chemistry, you will likely encounter tons of reactions that occur in aqueous solution (perhaps you are already drowning in them!). When ions are involved in a reaction, the equation for the reaction can be written with various levels of detail. Depending on which part of the reaction you are interested in, you might write a...
A molecular equation is sometimes simply called a balanced equation. In a molecular equation, any ionic compounds or acids are represented as neutral compounds using their chemical formulas. The state of each substance is indicated in parentheses after the formula.
[Huh?]
Let's consider the reaction that occurs between AgNO3 and NaCl . When aqueous solutions of AgNO3 and NaCl are mixed, solid AgCl and aqueous NaNO3 are formed. Using this information, we can write a balanced molecular equation for the reaction:
AgNO3(aq)+NaCl(aq)→AgCl(s)+NaNO3(aq)
[What kind of reaction is this?]
If we could zoom in on the contents of the reaction beaker, though, we wouldn't find actual molecules of AgNO3 , NaCl , or NaNO3 . Since AgNO3 , NaCl , and NaNO3 are soluble ionic compounds, they dissociate into their constituent ions in water. For example, NaCl dissociates into one ion of Na+ for every ion of Cl− ; these ions are stabilized by ion-dipole interactions with the surrounding water molecules.
A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions. We can find the net ionic equation for a given reaction using the following steps:
1.Write the balanced molecular equation for the reaction, including the state of each substance.
2.Using your knowledge of solubility rules, strong acids, and strong bases, rewrite the molecular equation as a complete ionic equation that shows which compounds are dissociated into ions.
[I haven't learned about strong acids and bases yet!]
3.Identify and cancel out the spectator ions (the ions that appear on both sides of the equation).

Sulfuric acid, H2SO4(aq) , is a strong acid that completely dissociates into H+ and SO42− ions in aqueous solution. Sodium hydroxide, NaOH(aq) , is a strong base that completely dissociates into Na+ and OH− ions in aqueous solution. When H2SO4(aq) and NaOH(aq) are combined, the products are water and aqueous sodium sulfate, Na2SO4(aq) . This reaction is represented by the molecular equation below.
HA2SOA4(aq)+2NaOH(aq)→2HA2O(l)+NaA2SOA4(aq)

Table: Common Polyatomic ion the topic of acids and polyatomic ions, there is nomenclature of aqueous acids. Such acids include sulfuric acid (H 2 SO 4) or carbonic acid (H 2 CO 3). To name them, follow these quick, simple rules: If the ion ends in -ate and is added with an acid, the acid name will have an -ic ending.
