Hey,
I'm still a student, so I cannot guarantee that my answer is entirely correct, however, this is what my answer was on a similar question in a matsec paper:
> Since pepsin is an enzyme, which works best in acidic environment, such as the one provided i the stomach, no change/ reaction would be observed, because NaOH is an alkaline solution. Therefore, pepsin would not be able to work in an environment with such great pH difference to its optimum.
I hope that helped somehow although my answer is probably very late :P
Good luck,
Angelina

When pepsin and NaOH are added to solid egg white, pepsin will digest the proteins present in the egg white, breaking them down into smaller peptides. NaOH will help to maintain the pH balance for the enzymatic activity of pepsin. This can result in the egg white becoming partially liquefied as the proteins are broken down.

Liquid A Is added to liquid B in a beaker. As the liquids mix a white solid and several bubbles form inside t?
The white solid is a precipitate. The bubbles will be a gas. Without knowing which chemicals you are dealing with it's impossible to be more specific.
What solid is formed when sulfuric acid is added to PABA?
When sulfuric acid is added to PABA (para-aminobenzoic acid), a white solid known as p-aminobenzoic acid sulfate is formed. This is due to the sulfonation of the amino group on the PABA molecule.
Is borax liquid gas or solid?
white solid
What colour solid is silver phosphate?
Silver phosphate is a white solid.
Is PbCO3 a solid?
Lead(II) carbonate is a white solid.
What happens to egg white pepsin and hydrochloric acid after 6 hours?
The protein in the egg white gets digested.
What happens when bcl3 is added to water?
White fume is given out.
What happens when white vinegar is added to a crushed shell?
99 % of the shell is dissolved.
Where in the body would you find conditions like egg white pepsin and hyrochloric acid?
you can't find egg white in your body unless you have just eaten an egg however you can find pepsin and hydrochloric acid in your stomach

What happens when you mix Hydrochloric acid with ammonia?
When mixed together, hydrochloric acid and ammonia will react to form ammonium chloride, a white crystalline substance that is soluble in water. This reaction releases heat and is exothermic. It is important to handle these chemicals with care, as they are corrosive and can cause harm if not used properly.

What happens when water is added to white copper sulfate?
Its sulphate not sulfate and sorry im not sure my self
Is this a chemical change or physical change silver nitrate solution is added to another solution producing a white solid?
it is a chemical change
What is made when silver nitrate and sodium chloride is added together?
When silver nitrate and sodium chloride are added together, a white precipitate of silver chloride is formed due to a chemical reaction between the two compounds. This reaction is a classic example of a double displacement reaction where the silver cation from silver nitrate swaps places with the sodium cation from sodium chloride, resulting in the formation of insoluble silver chloride.
What happens when water is added to anhydrous copper II sulphate?
it changes colour from a white powder to a blue powder
What happens to proteins at a temperature above 50 degrees?
They begin to denature (sort of like an egg white turning solid as it is cooked).
