Определение массовой процентной доли CuSO4∙5H2O методом йодометрии (МCuSO4∙5H2O =
249,68 г/моль). Определите фактор эквивалентности анализируемого вещества и
стехиометрическое соотношение (s), приведите значение Е(CuSO4∙5H2O). Рассчитайте
массовую процентную долю CuSO4∙5H2O через Е(CuSO4∙5H2O), М(CuSO4∙5H2O) и по титру
