Substances dissolved in water react better because :
Correct answer: C. Water dissolve them in ions
- A. Water brings them close
- B. Water helps them in bonding
- C. Water dissolve them in ions
- D. Water reacts with them
Explanation
When substances dissolve in water, they often undergo a process called hydration, where the water molecules surround and separate the individual particles of the substance, resulting in the formation of ions. This process is known as dissociation or ionization. Water has a polar molecular structure, meaning it has a slightly positive charge on one end (hydrogen) and a slightly negative charge on the other end (oxygen). This polarity allows water molecules to interact with charged particles (ions) and polar molecules by forming hydrogen bonds.

About Salts and Hydrolysis
Salt hydrolysis explains how ions from weak acids or weak bases react with water and affect the pH of a solution. The content covers acidic, basic and neutral salts, hydrolysis equations, Ka, Kb and Kw relationships, degree of hydrolysis and buffer connections, distinguishing hydrolysis from simple acid-base neutralisation.
