MacBook solution. Part II. Equilibria Involving Sparingly som ving Sparingly Soluble Salts form to cloudy yellow clear solution 11 MA, CO3+ a CO₂ + 0.01 AGNO Adding Nos reverse back Account for your observations O.IM HCI becomes were con forming a precipitat? .TH 13. The solution above with the adding of Account for your observations 14. Did the precipitated AgCl dissolve? Explain. The presipitete disolves after adding 15M NH₃, solution clear. 15. What effect did the addition of HNO, have on the contents of the test tube? Explain. Adding 6M HNO3 it's become more cloudy. (ompe precipitate) 16. What effect did the addition of NH, have on the contents of the test tube? Explain. The solutious go back to clear. 17. Explain the effect of the addition of Kl. 108

Please be as thorough in the explanation as possible. Thank you

Answer 1

11) Na, CO3 +2Ag Noz ->Nanoz +Ag2 C03 (Yellow) Yellow coloration is due to formation of silver carbonate 12) AgzCoz + 2HNO3 → 2Ag Noz & thot Co2 clear solution is due to formation of sitwer nitrate and lo, and water which all are coorless. 13) Agoloz t Hel → Agad + HNO 3 Whete ppto)

или/ии. white ppt of Agcl is the reason for cloudiness. 14) AgCl + 2NH3 + Ag (13)] CI clear sotulion Sit dear solution is due to dissolution of ppt of Aga..

15) [Ag (Nurs), la + 2HNO3 → Agcal thering Ppt.) On adding HNO3, the complex breaks down resulting is agair formation of I white pept. of Aga 16) Addia of Nit has been explained in stelp formation of complex Celear soduction) (17) Agnoz + KI Ag I J + Knoz deep Yellow Addition of KI causes formation of deep yellow ppt of Ag I un
