equal volume each of two sols of Agl, one obtained by adding `AgNO_(3)` to slight excess of Kl and another obtained by adding KI to slight excess of `AgNO_(3)` are mixed together . Then :
A
the two sols will stabilize each other

on adding AgNO_(3) solution into KI solution , a negatively charged colloidal sol is obtained when they are in :
each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: Colloidal Agl is prepared by adding Kl in slight excess to AgNO_(3) solution, the and particles migrate toward cathode under electric field. STATEMENT-2: Colloidal particles adsorb ions and thus becomes electrically neutral.
A colloidal solution of Agl is prepared by the following two methods : (a) Adding AgNO_3 to KI (aq) solution (b) Adding KI to AgNO_3 (aq) solution. Give reasons for the origin of charges.
When one mole of each of the following complex salts is treated with excess of AgNO_3 , which of them gives maximum amount of AgCl ?
Oleum is considered as a solution of SO_(3) in H_(2)SO_(4) , which is obtained by passing SO_(3) in solution of H_(2)SO_(4) When 100 g sample of oleum is diluted with desired mass of H_(2)O then the total mass of H_(2)SO_(4) obtained after dilution is known is known as % labelling in oleum. For example, a oleum bottle labelled as ' 019% H_(2)SO_(4) ' means the 109 g total mass of pure H_(2)SO_(4) will be formed when 100 g of oleum is diluted by 9 g of H_(2)O which combines with all the free SO_(3) present in oleum to form H_(2)SO_(4) as SO_(3)+H_(2)O to H_(2)SO_(4) If excess water is added into a bottle sample labelled as "112% H_(2)SO_(4) " and is reacted with 5.3 g NaCO_(3) then find the volume of CO_(2) evolved at 1 atm pressure and 300 K temperature after the completion of the reaction :
A sol is prepared by addition of excess of AgNO_(3) solution in KI solution . The charge likely to develop on colloidal particles is :
On adding AgNO_3 solution to 1 mole of PdCl_2 . 4NH_3 , two moles of AgCl are formed. The secondary valency of Pd in the complex will be
A solution containing 2.675 g of CoCl_3 .6NH_3 (molar mass = 267.5 g mol^-1 ) is passed through a cation exchanger. The chloride ions obtained in solution were treated with excess of AgNO_3 to give 4.78 g of AgCl (molar mass = 143.5 g mol^-1 ). The formula of the complex is : (At. mass of Ag = 108 u)
A reaction system in equilibrium according to reaction 2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g) in one litre vessel at a given temperature was found to be 0.12 mole each of SO_(2) and SO_(3) and 5 mole of O_(2) In another vessell of one litre contains 32 g of SO_(2) at the same temperature. What mass of O_(2) must be added to this vessel in order that at equilibrium 20% of SO_(2) is oxidized to SO_(3) ?
When 1 mol CrCl_3 .6H_2O is treated with excess of AgNO_3 , 3 3 mol of AgCl are obtained. The formula of the complex is:
