Which of the below statements IS TRUE/FALSE concerning hot gravity filtration as applied in recrystallization experiment? Please answer all parts: True False If a few crystals form on the filter paper during filtration they can be scraped into a flask and redissolved in half of the original amount of hot recrystallization before refiltering. True False To prevent premature recrystallization during filtration, the receiver flask and stemless funnel are preheated before pouring the hot solution. True False To prevent premature recrystallization, you should use at least 10-30% more recrystallization solvent than the minimum needed to dissolve the crude solid. True False Hot gravity filtration is applied to separate(remove) undissolved impurities from the hot solution. Please answer very soon will give rating surely All questions answers needed
