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.
Get Price25-02-2020· Hydrochloric Acid and Sodium Hydroxide Hello,you are in right place to know about the reaction between hydrochloric acid and sodium hydroxide. Hydrochloric acid is an acid because it has hydrogen ion.The formula for hydrochloric acid is HCl.It is a strong acid.
Get PricePhosphates 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.
