Titration to determine the empirical formula of zinc chloride Dec 7, 2023 · If the burette used for titration delivered less volume than the recorded volume of Zn2+ solution, it would lead to an underestimation of the volume of titrant added, and consequently, the number of moles of chloride ion determined would also be underestimated. In this experiment, we treat the water molecules as single units rather than breaking them down into H and O Example: Given the percent composition of hydrated zinc sulfate, as follows: % (per 100 g) Zinc powder was reacted with hydrochloric acid and heated to form zinc chloride. This clearly indicates that in zinc chloride, one Zn ion (Zinc) is combined with two Nov 14, 2022 · Describe the effect on the following: During your titration of Zinc Chloride lab, you discovered that the burette you used delivered less volume than the recorded volume of Z n2+ solution used in titration. In this video we'll write the correct formula for Zinc chloride (ZnCl2). To determine the empirical formula of zinc chloride, we would need to titrate the sample to determine the moles ofzinc ion and chloride ion.
