👉 In the context of physics and chemistry, a disintegrable substance is one that breaks down into smaller particles or components upon exposure to heat, pressure, or other conditions. It may also be broken down by chemical reactions with other substances. For example, in a reaction between water and sodium bicarbonate (NaHCO3), the sodium ions (Na+) are released as a gas, while the carbonate ions (HCO3-) are dissolved into the solution. This process is known as dissolution
