Explanation:
<h3>H2SO4 + 2 NaOH = Na2SO4 + 2H20, </h3>
<h3>2 in sodium hydroxide </h3><h3>And 2 in water </h3>
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.

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%
