As a chemist for an agricultural products company, you have justdeveloped a new herbicide,\"Herbigon,\" that you think has thepotential to kill weeds effectively. A sparingly soluble salt,Herbigon is dissolved in 1 M acetic acid for technical reasonshaving to do with its production. You have determined that thesolubility product Ksp of Herbigon is 9.50×10−6. Although theformula of this new chemical is a trade secret, it can be revealedthat the formula for Herbigon is X-acetate (XCH3COO, where \"X\"represents the top-secret cation of the salt). It is this cationthat kills weeds. Since it is critical to have Herbigon dissolved(it won't kill weeds as a suspension), you are working on adjustingthe pH so Herbigon will be soluble at the concentration needed tokill weeds. What pH must the solution have to yield a solution inwhich the concentration of X+ is 6.00×10−3 M ? The pKa of aceticacid is 4.76.
