Solubility conversion problem
Thread Content
Everyone, I would like to ask: the book states that the solid-liquid ratio of the salt solution is 25%. How can this be converted into a weight percentage (wt%)? (Assuming the solubility of sodium chloride at 20 degrees Celsius is 36.0 g per 100 g of water.)
Is the solid-liquid ratio of the salt slurry 25%, on a volume percentage basis?
I’m sorry; I didn’t make it clear that it was a weight percentage
So can I understand it this way: 80g of NaCl is dissolved in 100g of water (assuming that the solubility of sodium chloride at 20 degrees Celsius is 36.0g per 100g of water, with a specific gravity of 1.2). The saturated solution weighs 136g, while the amount of NaCl that remains undissolved is 44g. Therefore, the solid-to-liquid ratio in this salt slurry is 32.3%. As for the weight percentage, isn’t it 80/136 = 58.8%?
Is the solid-liquid ratio the ratio of the weight of undissolved solids to the weight of the saturated solution, or is it the ratio to the solvent?
