This standardized NaOH solution was used for the whole experiment. Elements and … Because of the complexity of the formula, we will refer to the KHC4H4O6 as KHT in order to simplify the equation. 1. Repeat steps 1 to 4 twice to obtain a total of 3 trials. If 1000 L of a certain wastewater contains Cd 2+ at a concentration of 1.6E–5 M, what concentration of Cd 2+ would remain after addition of 10 L of 4 M NaOH solution? Compute and record the average molarity of the NaOH solution. 010 L = . II. Each midshipman in the pair should perform the following steps, so that each midshipman analyzes at least Rinse the buret with a small portion (~5 mL) of the NaOH solution, discard this rinse. Equation is already balanced. 1.2. Reaction Information. Ask Question Log in. 0-1. These two atoms combine with the oxygen from the NaOH to form H2O, which is the chemical formula for water. when KHC4H4O6 is obtained by mixing enough KOH it created hydrogen and from CHEMISTRY 1110 at University of California, Berkeley what did it do?
