Tracheids have a dual function of support and water conduction, whereas vessel elements, except perhaps for some primitive types, function in conduction only. Both cell types are readily preserved in fossils and are easily recognized by their secondary wall thickenings. What are the similarities and differences between tracheids and vessels?

Answer. Curd and acidic substances contain acids. If we put them into metals, the acids will react with metal, so we can’t put them into metals. Steel and plastic don’t react with acids. Metal + Acid → Salt + Hydrogen. Lactic acid is an organic acid that contains the -COOH group. Hence, it is a weak acid due to the presence of this group.

Curd and other sour substances contain acids. Therefore, when they are kept in brass and copper vessels, the metal reacts with the acid to liberate hydrogen gas and harmful products, thereby spoiling the food.acid + metal → salt + Hydrogen gas

Alloy 20 is an enriched grade of stainless steel, designed specifically for use with dilute (up to 30 percent by weight) sulfuric acid at elevated temperatures. It can also be used for nitric and phosphoric acid systems as well as for all systems for which T316SS is suitable. Alloy 400

copper reacts with moist air and forms a layer of copper carbonate which is basic in nature therefore lemon or turmeric is used to remove the copper carbonate layer . since lemon and turmeric are acidic in nature day neutralize the copper carbonate layer. How do you clean a copper vessel with a lemon? To Skip to content FAQS Clear

1. Stainless steel is an alloy of iron ; with carbon, chromium and nickel. 2. The conductivity of copper is higher than that of iron in steel. Copper heats uniformly and faster. The time for cooking is reduced, as a result it saves fuel. Hence, the stainless steel vessels in kitchen have copper coating on the bottom. ← Prev Question Next Question →
