What is pH of a solution if you mix: 10 ml of 0.2 M HCl and 35 ml of 0.15 M NaOH. 200 ml of 20 mM NaOH and 100 ml of 40 mM HCl. 200 ml of 250mu M NaOH and 25 ml of400 mu M H_2 SO_4. How many grams NaCl is is needed to prepare 600 mL of 250 ppm Na solution?
"Prepare 500 mL of a 0.1 M sodium hydroxide solution by dilution of a 1 M sodium hydroxide stock reagent or from solid NaOH. This dilution need only be performed to 5% accuracy, that is, using a graduated cylinder and an Erlenmeyer flask." 1. Explain why it is not necessary and even not desirable to perform the preparation of 1 M sodium hydroxide operation with higher accuracy. "Add the analyte to the beaker and fill with distilled deionized water to...
