WebApr 5, 2024 · Since it is a strong acid, on dilution in water the hydrochloric acid will dissociate into hydrogen ions and chloride ions, and this is an exothermic reaction. Complete answer: We know that there are two types of reactions based on the temperature, i.e., exothermic reaction and endothermic reaction. WebClick here👆to get an answer to your question ️ Which of the following are exothermic processes?(i) Evaporation of water.(ii) Dilution of an acid (H2SO4) .(iii) Reaction of water with quick lime.(iv) Sublimation of camphor (crystals).
WebBest. •. The term you're looking for is called "enthalpy of dilution" and depends on how strongly the molecules interact with each other relative to how strongly they interact with … WebApr 7, 2024 · When concentrated sulphuric acid is diluted with water to obtain dilute sulphuric acid, a huge amount of energy is released. Thus, this reaction is an exothermic process. Water vapour releases heat and changes its state from vapour to liquid to through condensation. Thus, condensation of water is possible through the evolution of heat energy.
WebAug 12, 2024 · (ii) It is because process is highly exothermic. If water is added to acid, it generates huge amount of heat which may cause accident but if acid is added dropwise to water, then the heat is absorbed by the solution. Question 11. A student dropped few pieces of marble in dilute hydrochloric acid, contained in a test-tube. WebJun 18, 2024 · Yet, since this is just based on personal experience, I'd like to give you some scientific evidence. In Caustic Soda Handbook of OxyChem, there is an example saying "the approximate resulting temperature of final solution after diluting 50 % N a O H at 120 ∘ F ( 48.9 ∘ C) to 20 % using water at 80 ∘ F ( 26.7 ∘ C) is 143 ∘ F ( 61.7 ∘ ...
WebThe reaction is exothermic, but the dilute acid is in excess and the rise in temperature is only of the order of 3.5˚C. There is some acceleration of the reaction rate due to the rise in temperature. Some students might notice the flask becoming slightly warm and they could be asked how this would affect the rate of reaction, and how they ...

My understanding from Le … david steinberg university of utahWebApr 6, 2024 · A.Dilution of sulfuric acid: In this reaction, acid is added to water to form a dilute solution of dilute sulfuric acid. Because of the formation of hydrogen bonds with water, energy is released by molecules and later, the water absorbs the same energy. So, this reaction is an exothermic one. Option (A) is correct. gastric pathogen panelWebAug 23, 2024 · If the initial dissolution process is exothermic (ΔH < 0), then the dilution process is also exothermic.
