Abstract
Предлагаемый способ определения массовой части сернокислого и азотнокислого кальция в концентрированной аммиачной селитре с доломито-сульфатной добавкой заключается в том, что растворяют пробу селитры в этиловом спирте, отделяют осадок сернокислого кальция, не растворенный в спирте, с помощью фильтрования, и осуществляют комплексонометрическое титрование ионов кальция с темно-синим хромовым индикатором.
