What is the formula unit for the ionic compound sodium iodide?
The formula unit for sodium iodide is NaI. This compound is made up of sodium cations (Na+) and iodide anions (I-), which combine in a 1:1 ratio to form a neutral compound.
Two solutions mixed to make silver iodide?
Silver nitrate solution and potassium iodide solution can be mixed to form silver iodide due to a double displacement reaction where the silver ions from silver nitrate react with the iodide ions from potassium iodide to form insoluble silver iodide precipitate. The balanced chemical equation for this reaction is: AgNO3 (aq) + KI (aq) → AgI (s) + KNO3 (aq).
Silver nitrate solution is reacted with sodium iodide solution?
This is a precipitation reaction. Halides of silver are insoluble in water (except silver fluoride) whereas all nitrates are soluble in water. Sodium salts are soluble. Thus, silver iodide is the precipitate. Formula: AgNO3(aq) + NaI(aq) -> AgI(s) + NaNO3(aq)
Sodium iodide reacts with phosphoric acid?
The reaction between sodium iodide and phosphoric acid forms sodium dihydrogen phosphate, hydrogen iodide gas, and water. It is a double displacement reaction where the ions in the reactants swap partners to form the products. This reaction is commonly used in the synthesis of certain organic compounds.
What does sodium iodide and lead nitrate form?
Sodium iodide and lead nitrate react to form sodium nitrate and lead iodide. This is a double displacement reaction where the positive ions in the two compounds switch places. Lead iodide is insoluble and will precipitate out of the solution.
What happens when you mixed Lead Nitrate with Sodium Iodide?
When lead nitrate is mixed with sodium iodide, a solid precipitate of lead iodide is formed along with sodium nitrate. This reaction is a double displacement reaction where the cations of the two compounds switch partners to form the products. Lead iodide is a yellow precipitate that can be easily observed in the reaction mixture.
Formula of sodium plus Iodide?
The formula for sodium iodide is NaI. It is formed by the combination of sodium (Na) and iodide (I-) ions, with sodium donating an electron to iodine to form a stable compound.
Is iodide a compound?
Iodide is an ion formed from the element iodine, so it is not a compound.
What are the formulas for the ionic compounds named sodium iodide?
Sodium iodide is a compound and that is its name.
How do sodium and iodide combine?
Sodium and iodide combine to form sodium iodide (NaI), a white solid with similar properties to table salt. This combination occurs through an ionic bond, with sodium donating an electron to iodide to achieve stability. Sodium iodide is commonly used in medicine, photography, and chemical synthesis.
What does sodium and iodine make?
Sodium Iodide. Here is the balanced reaction eq'm 2Na(s) + I2(s) = 2NaI(s)
What is the reactivity of iodine with other elements?
Iodine is moderately reactive with certain elements. It can react with metals like sodium and potassium to form metal iodides. It can also react with nonmetals like hydrogen to form hydrogen iodide. However, iodine is less reactive compared to elements like chlorine or oxygen.
Is sodium iodide aqueous?
Yes it is Aqueous !! You need to look up the solubility table to see for yourself !! Have fun !!
What is the name the ionic compound that forms when sodium and iodine pairs of elements are combined chemically?
The ionic compound that forms when sodium and iodine combine chemically is sodium iodide (NaI). Sodium gives up an electron to iodine, forming a positively charged sodium ion and a negatively charged iodide ion, which then attract each other to form the compound.
Is sodium iodide soluble?
Yes, sodium iodide (NaI) is highly soluble in water. It dissolves readily to form a clear solution.
When an aqueous solution of lead(II) nitrate is mixed with an aqueous solution of sodium iodide an aqueous solution of sodium nitrate and a yellow solid lead iodide are formed.?
Lead(II) nitrate and sodium iodide undergo a double displacement reaction to form sodium nitrate and lead(II) iodide, which is a slightly soluble yellow solid. The balanced chemical equation for this reaction is: Pb(NO3)2(aq) + 2NaI(aq) -> 2NaNO3(aq) + PbI2(s)
How does iodine bond with other elements such as sodium?
Iodine can bond with sodium through an ionic bond to form sodium iodide. In this bond, iodine gains an electron to achieve a stable electron configuration and becomes negatively charged (I-), while sodium loses an electron to become positively charged (Na+). The attraction between the oppositely charged ions results in the formation of the ionic compound sodium iodide.
