If pH (± 0.5 pH units) strips were used to determine the equivalence point at pH=8.5. What is the relative error (%) in pH at the equivalence point? I assumed it should be 0.5/8.5 * 100 = 5.88, rounded to 5.9 for sig figs. but I got the answer wrong. Please help and let me know how to solve this.
20.0 mL water sample was titrated with 0.0100 M EDTA solution that required 14.50 mL for CaCO3 hardness. The total hardness of the water sample in terms of CaCO3 (MW = 100.1 g/mole) in parts per million is _________? Note: Express final answer using least number of significant figures. 2. If 35.2 mL of EDTA solution is required to reach the endpoint with 0.3120-g of primary standard grade CaCO3 (MW = 100.1 g/mole), the normal concentration of the EDTA (MW = 292.24) solution is _________ N?
An analyst determines the Cl^- content of rain water with ion chromatography. The data for the calibration line in the range 5 to 50 milli equivalents per liter (mEq/L) is shown in the table below. Additionally, a blank sample was analysed 5 times and the following results obtained: 1.1, 0.5, 0.1, 0.9 and 1.2 ppm Ct Calculate the detection limit (DL) for the method with a 98.3% confidence level.
