When concentrated acid is diluted with water the outside of the flask becomes extremely warm. Is the dilution process exo or endothermic?
Homework Answers
When concentrated acid is diluted with water , large amount of heat is released which makes the outside of flask extremely warm. We know that the process which involve release of heat is called exothermic process.
So, it means dilution of concentrated acid is an exothermic process.

Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...

D. Addition of sulfuric acid to a flask of water is observed to increase the temperature of the flask. The creation of the mixture can be thought of as breaking interactions between water molecules (i.e., water - water interactions), breaking interactions between sulfuric acid molecules (i.e., sulfuric acid - sulfuric acid interactions) and forming new interactions between water and sulfuric acid (i.e., water - sulfuric acid interactions). Which of the following is true? Circle and explain your answer to receive...

A flask has a mass of 78.23 g when empty and 593.63 g when filled with water. When the empty flask is filled with concentrated sulfuric acid, H2SO4, its mass is 1026.57 g. What is the density of concentrated H2SO4? Assume water has a density of 0.998 g/mL at the temperature of the measurement.

When lithium iodide (LiI) is dissolved in water, the solution becomes hotter. [ Hint: According to Hess’s Law, the overall enthalpy change upon solution formation is the sum of the changes in enthalpy for each step. Recall which two terms on the right hand side of the equation below combine to make the heat of hydration. ] Hsolution = Hsolute + Hsolvent + Hmixing a.) Is the dissolution of LiI endothermic or...
