Hydrochloric acid being a very good reducing agent, will interfere with the titrations and be oxidised to chlorine by potassium permanganate. Hence sulfuric acid is used, and not HCl.
Using hydrochloric acid instead of sulfuric acid in the Molisch test would yield a different result. Hydrochloric acid does not have the same dehydrating properties as sulfuric acid, so it would not lead to the formation of a purple ring with carbohydrates. The Molisch test relies on the dehydrating ability of sulfuric acid to break down carbohydrates into simpler compounds, which then react with alpha-naphthol to produce the purple ring.
Hydrochloric acid is commonly used over sulfuric acid in certain applications because it is less aggressive, safer to handle, and produces less toxic fumes. Additionally, hydrochloric acid is more efficient at dissolving certain types of materials compared to sulfuric acid.
Sulfuric acid is commonly used in redox titrations because it is a strong acid and does not participate in the redox reactions. Nitric acid (HNO3) can act as an oxidizing agent itself, which can interfere with the redox titration process by introducing additional reactions.
Using sulfuric acid in place of hydrochloric acid for a sulfate test can produce inaccurate results due to the formation of insoluble precipitates with some sulfates. This can interfere with the detection of sulfate ions in the test solution. Hydrochloric acid is preferred as it reduces the likelihood of forming these precipitates, ensuring a more reliable sulfate test.
Sulfuric acid cannot be used in place of hydrochloric acid in the barium chloride test because sulfuric acid would react with barium chloride to form insoluble barium sulfate. This would interfere with the precipitation reaction used to detect the presence of sulfates in the sample. Hydrochloric acid is preferred because it does not interfere with this reaction.

HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.
Nitric acid is not used in permanganate titrations because it can react with permanganate ions and reduce them before they can oxidize the analyte. This interference can lead to inaccurate results in the titration process. Instead, sulfuric acid is often used as the acidifying agent in permanganate titrations.
No, it is not recommended to clean nichrome wire with sulfuric acid as it can cause corrosion and damage to the wire. It is safer to use a mild solvent or a cleaning agent specifically designed for cleaning metal surfaces.
Yes, diluted nitric or sulfuric acid can be used instead of hydrochloric acid in Sahli's acid hematin method. However, the choice of acid may affect the sensitivity and accuracy of the results, so adjustments may be needed in the protocol or interpretation of the test. It is advisable to validate the method with the alternative acid before routine use.
Using hydrochloric acid instead of sulfuric acid in a titration may result in inaccurate results because the equivalence point may be difficult to identify due to the similar dissociation behavior of the two acids. Additionally, hydrochloric acid can partially evaporate during the titration process, leading to a loss of accuracy in determining the concentration of the solution being analyzed.
Hydrochloric acid (HCl) may react with the potassium permanganate produced, leading to undesirable side reactions. Sulfuric acid (H2SO4) is chosen because it is a non-oxidizing acid that maintains the stability and purity of the final product.
Mohr's salt (ammonium iron(II) sulfate hexahydrate) is used instead of ferrous sulfate in redox titrations because it is more stable and less prone to oxidation by air compared to ferrous sulfate. This helps in achieving more accurate and reliable results in redox titrations.
