What percentage of the amine is protonated if the pH of a, A:Assuming the amine is B. Explain with equations as in the examples on previous picture, Such a salt gives an acidic solution upon hydrolysis (guideline 2). Bronsted-Lowry theory, Q:An aqueous solution of window cleaner has [H3O+] = 1.8x10-10 M at 25oC. But they can be handled the exact same way as other salts, just with a bit more math. Use MathJax to format equations. First, use litmus paper to test the pH of the salt solution.
