CBSE Class 11 science: Common Ion Effect Videos | Equilibrium

•   Sir, Can you please explain the method for solving buffer based and PH based questions in equillibrium
• What is the common ion effect?
• What is a buffer solution?
• How do buffer solutions work?
• The K_sp for AgCl is 1.8 x 10^-10. If Ag⁺ and Cl^- are both in solution and in equilibrium with AgCl. What is [Ag⁺] if [Cl^-] = .020 M?
• The K_sp for AgCl is 1.8 x 10^-10. If Ag⁺ and Cl^- were both present at 0.0001 M, would a precipitate occur?
• Iron (III) nitrate has a solubility of 0.15 M. Find concentration of the ions in solution.
• The K_sp for Ag₂CrO₄ is 9x10^-12 M³. What is the molar solubility of Ag₂CrO₄ in pure water?
• Calculate [Ag⁺], when 0.03 mole of KBr is added to one liter saturated solution of AgBr. Given K_sp of AgBr =5.0x10^-13
• A solution is formed by combining 0.025 mol CaCl₂ and 0.015 mol Pb(NO₃)₂ producing one litre of solution. Will PbCl₂ precipitate in this solution?
