Sodium Phosphate And Hydrochloric Acid Are Mixed

*4054381962* READ THESE INSTRUCTIONS FIRST

3 When aqueous sodium thiosulfate and dilute hydrochloric acid are mixed, a precipitate of insoluble sulfur is produced. This makes the mixture difficult to see through. Na 2 S 2 O 3 (aq) + 2HCl (aq) → S(s) + 2NaCl (aq) + H 2 O(l) + SO 2 (g) The time taken for the cross to disappear from view is measured.

Phosphorus, Acid Hydrolyzable - Hach Company

Phosphates in condensed inorganic forms (meta-, pyro-, or other polyphosphates) are converted to reactive orthophosphate before measurement. The sample is pretreated with acid and heat to hydrolyze the condensed inorganic forms to orthophosphate. Orthophosphate reacts with molybdate in an acid medium to produce a mixed phosphate/molybdate complex.
