what's the easiest way to go abouts figuring (using basic lab tools) out the acidic % of a certain type of food, especially if it's a solid not a liquid. Would you still titrate it somehow? Help! please! Thanks
Weigh the food then dissolve it in water. Titrate with very dilute sodium hydroxide.That will tell the number of equivalents. If you know what acid you are looking for (citric in lemons?), you can turn that equivalence into moles, then into mass. Divide the mass of the acid by the mass of the entire thing you dissolved then multiply by 100 and you have % acid.chris111 said:especially if it's a solid not a liquid.
I'd pulverize it thoroughly, soak it, then put it in a funnel with filter paper and wash it, collecting the water.chris111 said:But how would i "Dissolve the item in water"...lets say it's a pickle? Would I just grind it up till its in smaller chunks? Would that be an accurate way? thanks for ur help btw.
