(d) Student should be able to state the relationship between the size of the
solute and the time taken for it to dissolve correctly.
The finer the size of the solute particles, the faster the rate of
dissolving/Semakin halus size partikel bahan larut, semakin cepat kadarketerlarutanya.//The coarser the size of the solute particles, the slower the rate of
dissolving / Semakin kasar size partikel bahan larut, semakin lambatkadar keterlarutannya
