2Na2S2O3 + I2 --> 2NaI + Na2S4O6
Sodium thiosulfite reacts with iodine in an oxidation-reduction reaction, causing it to appear colorless in the presence of starch indicator solution.
Ionic equation for sodium thiosulfate Ionic equation for sodium thiosulfate
I2(aq)+2Na2S2O3(aq)---------------->2NaI(aq) + Na2S4O6(aq)
This equation is F2 + 2 NaI -> I2 + 2 NaF.
aluminium does not react with water but it reacts with steam
you have to write... 2KI + Cl2 = 2KCl + I2
2KI + Cl2 = 2KCl + I2
180g I2
Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.
Cl2 + 2NaI ---> 2NaCl + I2
aluminium does not react with water but it reacts with steam
fluorine reacts with water veryviciously the chemical equation for it is fluorine + oxygen = fluorine oxide
you have to write... 2KI + Cl2 = 2KCl + I2
2KI + Cl2 = 2KCl + I2
potassium iodide
180g I2
Solid sodium iodide reacts with water to form sodium ions and iodide ions. No further reactions occur because this compound is a salt of a strong acid and a strong base. Thus, the overall reaction is NaI(s)=> Na+ + I-
Equation: O22- + I- ----> O2- + I2
Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.
The equation is H2 + F2 -> 2 HF.
The chemical equation is:2 KI + Pb(NO3)2 = 2 KNO3 + PbI2(s)
