Commercial processors of potatoes remove the skin by using 10-20% by mass solution of sodium hydroxide. The potatoes are soaked in the solution for a few minutes at 60-70*C, after which the peel can be sprayed off using fresh water. You pipette 25.00mL of NaOH and find it has a mass of 25.75g. Then you titrate the basic solution against 1.986 mol/L HCl, and find it requires 30.21mL of acid to reach an endpoint.
a) The mass percent of NaOH present must be a minimum of 10% for the solution to be used. Advise your supervisor whether or not the solution can be used to process more potatoes, explain and (calculate)
Thanks Guys and Gals
