Ans:

The vocabulary Dalal uses—terms like “reactivity,” “conservation,” “saturation,” “precipitation”—is introduced within context and repeated across problems. This incremental exposure helps students convert fluent everyday descriptions (it bubbled, it changed color) into precise scientific statements (gas evolved due to a chemical reaction, a color change indicates a pH shift). Such translation is central to scientific thinking: it makes subjective observation communicable and testable. viraf j dalal chemistry class 8 icse solutions
