AI Thread Summary

To calculate the theoretical yield of polysuccinimide (PSI) synthesized from aspartic acid, begin with the balanced chemical equation for the reaction. The stoichiometry of the reaction will determine the molar ratios of aspartic acid to polysuccinimide. Given that 10g of aspartic acid was used, convert this mass to moles using its molar mass. Then, apply the stoichiometric ratios from the balanced equation to find the expected moles of PSI produced. Finally, convert the moles of PSI back to grams to determine the theoretical yield. The actual yield of 7.3g can then be compared to the theoretical yield to calculate the percentage yield of the reaction.

Hello everyone,
I am trying to find how to calculate the theoretical yield of polysuccinimide I synthesized from the aspartic acid. I added 10g of Asp and i took 7,3g of PSI. Someone who knows how to find the yield?

On a basic level this is a simple HS level stoichiometric question. Start with the reaction equation.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
