What would happen if MnO2 was mixed with KI and 9 M sulfuric acid?
KI+MnO2+H2SO4=KI+MnSO4+KHSO4+H2O
When 0.500 l of a 1.00 m solution of pb no3 2 is mixed with an excess of 1.00 m solution of ki how many grams of lead II iodide are formed?
approx 2.4354g
What is the role of KI in the estimation of aniline?
ki is added to liberate iodine gas . this liberated iodine gas was then titrated with sodium thiosulphate to give a permanent white precipitate. this white precipitate indicates the endpoint of the titration..
Will a precipitate form if solutions of the soluble salts AgNO3 and KI are mixed?
Yes, AgI is insoluble, therefore will form a precipitate.
If PbNO3 lead nitrate is mixed with KI potassium iodide what will be the precipiate?
Pb(NO3)2 + 2KI -----> PbI2 + 2KNO3
What is the balanced equation for potassium iodide and H2O2 solution?
H2O2 + 2 KI --> 2 KOH + I2
What is the equation for the reaction between KI and H202?
There is no real "net ionic" equation, as KI is a catalyst that decomposes H2O2. The "slow step" is H2O2 + I- --> OI- + H2O The "fast step" is H2O2 + OI- --> H2O + I- O2 The overall is: 2 H2O2 --> 2H2O + O2
Why is KI a catalyst for H202 decomposition but KBr and KCl aren't?
The mechanism of catalysis involves the I- ion only. The mechanism is: H2O2 + I- --> IO- + H2O H2O2 + IO- --> I- H2O O2 Second step regenerates the I- ion (thus acts as a catalyst). This reaction is first order wrt to both H2O2 and I-. Notably exothermic reaction. Must be in a medium which allows formation of I-, ie dissociation of KI. Water is a wonderful example.

KI+MnO2+H2SO4=KI+MnSO4+KHSO4+H2O
When 0.500 l of a 1.00 m solution of pb no3 2 is mixed with an excess of 1.00 m solution of ki how many grams of lead II iodide are formed?
approx 2.4354g
What is the correct formula for potassium and Iodine?
Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". The formula for the compound formed between potassium and iodine, however, is KI.
What is the name of the binary compound formed from pottasium and iodine?
KI or potassium iodide. See the related link for more information.
When was uno formed and who was the secretary general of uno?
ban ki moon

What content of potassium iodide is present in naphthalene?
Nothing, Naphthalene is an organic compound and can not mixed with ionic compound KI.
If PbNO3 lead nitrate is mixed with KI potassium iodide what will be the precipiate?
Pb(NO3)2 + 2KI -----> PbI2 + 2KNO3
Will a precipitate form if solutions of the soluble salts AgNO3 and KI are mixed?
Yes, AgI is insoluble, therefore will form a precipitate.
