All the following are acid ionization reactions except
kompoz [17]

A substance that reacts with certain metals to produce salts and releases hydrogen ions into water. Acids give certain dyes a reddish tint and have a sour flavor. Some body-produced acids, such as stomach acid, can support organ function. Hydrochloric acid is a kind of acid.

What is Ionization Reaction?

A neutral atom or molecule can become electrically charged atoms by obtaining or losing a free electron, which is the definition of ionisation. Ionization takes place during a chemical reaction. An atom or molecule must either lose or gain electrons in order to ionise; the electron that is gained or lost creates an ion. An anion is a negatively charged atom or molecule that has gained an electron.

The atom or molecule that gains a free electron but loses it becomes positively charged and is known as a cation. Energy is either released or gained during ionisation.

An aqueous solution has a molality of 3. 64 kcl. what is the the mass percent of kcl in the solution? enter your answer to three
Sliva [168]

The mass percentage of KCl solution is 21.34%

Calculation,

Given molality of KCl aqueous solution =  3. 64  m =  3. 64 mole/ Kg

It means 3. 64 mole of solute present in 1Kg of solvent

or ,  3. 64 mole of solute present in 1000 g of solvent ( water )

Mass of solute ( KCl ) =  3. 64 mole×74.55 g/mole =271.3 g

The total mass of solution ( KCl + water ) = 271.3 g + 1000 g = 1271.3 g

Mass percentage is equal to percentage of mass of solute present in total mass of solution.

Mass percentage = 100×271.3 g/1271.3 g = 21.34%
