Welcome back — been a while! Let's pick up where you left off. Here are the observations and conclusions for the exercises on mixture C: a) Observation: Solid C dissolves in distilled water to form a colorless solution. Blue litmus paper turns red, and red litmus paper remains red. Conclusion: The solution is acidic. b) i) Observation: To the first portion, adding NaOH_(aq) dropwise produces a white precipitate. The precipitate dissolves when excess NaOH_(aq) is added, forming a colorless solution. Conclusion: Zn^2+, Al^3+, or Pb^2+ ions are present. ii) Observation: To the second portion, adding NH_3(aq) dropwise produces a white precipitate. The precipitate dissolves when excess NH_3(aq) is added, forming a colorless solution. Conclusion: Zn^2+ ions are present. iii) Observation: To the third portion, adding BaCl_2(aq) produces a white precipitate. The precipitate remains insoluble when dilute HCl is added. Conclusion: SO_4^2- (sulfate) ions are present. iv) Observation: To the fourth portion, adding Fehling's solution A and B and boiling, a brick-red precipitate forms. Conclusion: A reducing sugar is present. Send me the next one 📸
