Few days ago, my chemistry teacher taught me on coagulation of latex.
Something just make me curious and i asked my chemistry teacher to explain but she can't.
So, I just wanna ask...
Why acids can speed up the coagulation of latex by neutralizing the negative charge on protein membrane?
My teacher told me that the hydrogen ions from the acids neutralizes the negative charges of the protein membrane.
But why ammonia solution which is a base also has ammonia ions which is positive ions having positive charges cannot neutralizes the negative charges?
I tried to find it out on many resource in internet but it seemed not working.
Anyone can help me out?
