Arsenous sulphide sol is prepared by passing H_2S through asenous oxide solution the charge developed on the particles is due to adsorption of
A metal nitrate reacts with KI to give a black precipitate which addition of excess of KI converts into orange colour solution. The cation of metal nitrate is:
On adding AgNO_(3) solution to KI solution, a negatively charged colloidal sol will be formed in which of the following conditions ?
On addition of AgNO_3 solution to 1M CoCl_3. 5NH_3 solution, how many moles of AgCl are produced ?
When a copper wire is dipped in aqueous AgNO_(3) solution, the solution turns blue. The reason for this is
AgCl is less soluble in AgNO_(3) solution than in pure water. Explain.
A complex compound of cobalt contains five NH_(3) molecules. One nitro group and two chloride ions for one Co atom. One mole of this compound produces three mole ions in aq. solution. On reacting with excess of AgNO_(3) solution, two moles of AgCl get precipitated. EAN, of central atom of the complex is
