- What is the molar solubility of AgCl (Ksp = 1.80 × 10⁻¹⁰) in 0.410 M NH₃? (Kf of Ag(NH₃)₂⁺ is 1.7 × 10⁷) (Gpt/ai wrong answer not allowed) Ans should correctarrow_forwardWhen a small amount of AgCl(s) is added to a saturated solution of AgCl at constant temperature, then a.) the value of Ksp for AgCl(s) decreases b.)additional AgCl(s) dissolves into the solution c.)the value of Ksp for AgCl increases d.)the value of Ksp for AgCl(s) remains the same e.)less AgCl(s) precipitates from the solutionarrow_forwardPractice5: Standard solution of Na2CO3 was prepared by dissolving 0.53 g in 100 ml of water. Then 10 ml of this solution requires 9 ml of HCl for titration. Later 10 ml of unknown NaOH solution require 8 ml of same HCl for titration. Calculate strength of unknown NaOH solution in g/lit.arrow_forward
- Why is the pH of the 0.1 M acetic acid-sodium acetate buffer solution different from that of 0.1 M HC2H3O2? Be specific.arrow_forwardWhat volume, in milliliters, of 0.210 M NaOH should be added to a 0.125 L solution of 0.025 M glycine hydrochloride (p?a1=2.350, p?a2 = 9.778) to adjust the pH to 2.61? Please explain. Please type answer note write by hend.arrow_forwardA buffer solution made with NH3 and NH4Cl has a pH of 10.0. Which procedure(s) could be used to lower the pH?arrow_forward
- You have a weak acid concentration of 0.120 M and the conjugate base concentration is 0.100 M. What is the pH of this buffer? The Ka of this weak acid is 1.24x10-8 answer is 7.83, please explain how with stepsarrow_forwardIn lab, you will be provided with a 1.8 M acetic acid solution (CH3COOH) and solid sodium acetate trihydrate (NaOOCCH3 3H2O). You want to make 100.0 mL of a 0.5 M acetic acid buffer at pH 5.00. How many grams of sodium acetate trihydrate, and what volume (mL) of the 1.8M acetic acid solution and deionized water should you combine? The pKa of acetic acid is 4.75. Show all work.arrow_forwardA solution of PbI2 has an iodide concentration [I-]=3.0 x 10^-3 Write out the equilibrium reaction for the lead iodide (make sure to label with (s), (aq), and to balance equation).arrow_forward
