During the experiment "Estimation of Ca2+ and Mg2+ in a given sample of water by complexometric titration with a standard solution of EDTA," the _______ ions are removed from the given water sample by addition of _______ in the form of __________.Ca, NaOH, CaCO3Mg, NaOH, CaCO3Mg, NH4OH, Ca(OH)2Mg, NaOH, Mg(OH)2

Problem: A water sample containing calcium ions (Ca²⁺) is titrated with a 0.01 M EDTA solution. If 25.0 mL of the water sample required 15.0 mL of the EDTA solution to reach the end point, calculate the concentration of calcium ions in the water sample.

What is the function of EDTA (ethylene diamine tetraacetic acid) in complexometric titration?a) To increase the concentration of calcium ionsb) To complex with magnesium ions in the water samplec) To titrate the buffer solutiond) To stabilize the pH of the water sample

Solve: 1. A sample of tap water containing magnesium ions (Mg²⁺) is titrated with a 0.02 M EDTA solution. It takes 10.0 mL of the EDTA solution to titrate 50.0 mL of the water sample. Calculate the concentration of magnesium ions in the water sample. 3 marks 2. A 50.0 mL sample of wastewater is titrated with a 0.02 M EDTA solution to determine the concentration of magnesium ions (Mg²⁺). It requires 22.5 mL of the EDTA solution to reach the end point. Calculate the concentration of magnesium ions in the wastewater sample. 3 marks Problem: You are titrating a 50.0 mL solution of an unknown concentration of chloride ions (Cl⁻) with 0.100 M silver nitrate (AgNO₃) using a silver/silver chloride electrode. The standard electrode potential for the silver/silver chloride electrode is E∘=0.222 V. Calculate the potential of the solution at the following points:
