how do you explain the difference in time for dissolving the fine vs coarse salt crystals .
NAME_ REPORT FOR EXPERIMENT 9 (continued) B. Relative Solubility of a Solute in Two Solvents 1. (a) Which liquid is denser, decane or water? (b) What experimental evidence supports your answer? 2. Color of iodine in water: Color of iodine in decane: 3. (a) In which of the two solvents used is iodine more soluble? (b) Cite experimental evidence for your answer. Miscibility of Liquids 1. Which liquid pairs tested are miscible? 2. How do you classify the liquid pair decane-H0, miscible or immiscible? - Rate of Dissolving Versus Particle Size ,07 | LORS 1. Time required for fine salt crystals to dissolve 2. Time required for coarse salt crystals to dissolve - Since the amount of salt, the volume of water, and the temperature of the systems were identical in both test tubes, how do you explain the difference in time for dissolving the fine vs. the coarse salt crystals? Hot Rate of Dissolving Versus Temperature Under which condition, hot or cold, did the salt dissolve faster? w the texture of the salt crystals wereExplanation / Answer
fine salt has more surface area than coarse salt.
coarse salt is large crystal compare to fine salt, so water percolation is slow to dissolve the salt.
surface area based explanation is more relevant here, because if we grind coarse salt we will end up with fine salt which will be having more surface area and interaction between solvent( water ) and salt particles is high hence speed dissolution is expected.
