core practical-osmosis in potatoes cp3

Question 1

CP3-prepare potatoes- cut 6 similar pieces blot them dry and weigh them
CP3-run experiment-place each piece into test tube with sucrose(sugar) solutions with conc from 0% to 50%
CP3-record results-blot each dry and re-weigh

Answer 1

CP3-calculate percentage mass change-%chnage=(final value-starting value)/starting value x100
CP3-results-potato in weaker autos solution gain mass because water enters potato by osmosis,stronger solutions=lose mass as water leaves
