1. Please define water activity.2. Please define osmotic dehydration.3. Please define Raoult’s law.4. Write the water activity of ideal solutions equation according to Raoult’s law (Pleasespecify the meaning of each symbol in your equation).5. Modify the equation you write if solutes ionizes in the solution (Please specify themeaning of each symbol in your equation).6. Sodium chloride, β-D-fructofuranosyl α-D-glucopyranoside or sodium chloride - β-Dfructofuranosyl α-D-glucopyranoside solutions are used for dehydration of pumpkin.a) Estimate the water activity of 30% β-D-fructofuranosyl α-D-glucopyranoside solution.b) Estimate the water activity of 30% sodium chloride solution.c) Estimate the water activity of solution 20% sodium chloride and 20% β-Dfructofuranosyl α-D-glucopyranoside solution.d) What do you think about the effectivity of these solutions if the water activity of pumpkins are 0.945?
