Yellow precipitation shows the deposition of sulphur element.
The reaction between sodium thiosulfate and hydrochloric acid is a redox reaction, where the sulfur in thiosulfate changes oxidation state. The balanced equation for this reaction is: 2Na2S2O3 + 2HCl -> 2NaCl + SO2 + S + H2O.
When lead nitrate reacts with hydrochloric acid, a precipitation reaction occurs where lead chloride is formed as a white solid precipitate. This reaction can be represented by the chemical equation: Pb(NO3)2 (aq) + 2HCl (aq) → PbCl2 (s) + 2HNO3 (aq)
precipitation reaction
It's a precipitation reaction. A yellow precipitate will form, kind of like a bunch of little tiny yellow particles. At first, it will look a little like paint, but if you let it sit, the yellow particles will slowly drift to the bottom.
Solid Zinc reacting with Hydrochloric Acid is a single replacement Oxidation/Reduction reaction.

The formation of white precipitate indicates a chemical reaction occurred in the beaker that resulted in the precipitation of a solid product from the solution.
This is a precipitation reaction.
precipitation reaction
Yes, the solution of thiosulfate reaction can turn cloudy due to the formation of sulfur or sulfur particles during the reaction. This cloudiness is a result of the precipitate that forms when thiosulfate reacts with certain substances.

The reaction between zinc and hydrochloric acid is called a single replacement reaction. In this reaction, zinc displaces hydrogen from hydrochloric acid to form zinc chloride and hydrogen gas.
The word equation for the reaction of calcium and hydrochloric acid is: calcium + hydrochloric acid → calcium chloride + hydrogen.
Starch indicator is added after sodium thiosulphate in iodometric titrations to help visualize the endpoint of the reaction. Starch reacts with any excess iodine produced at the endpoint, forming a dark blue-black color, allowing for easier detection of when all the thiosulphate has reacted.
Hydrochloric acid (HCl) is used in the preparation of boric acid because it reacts with borax (sodium borate) to release boric acid. The reaction between hydrochloric acid and borax allows for the precipitation of boric acid, which can then be collected and purified.
