Chemistry

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 technicalreasons having to do with its production. You have determined thatthe solubility product Ksp of Herbigon is9.50×10−6.

Although the formula of this new chemical is a trade secret, itcan be revealed that the formula for Herbigon is X-acetate(XCH3COO, where \"X\" represents the top-secret cation of the salt).It is this cation that kills weeds. Since it is critical to haveHerbigon dissolved (it won't kill weeds as a suspension), you areworking on adjusting the pH so Herbigon will be soluble at theconcentration needed to kill weeds. What pH must the solution haveto yield a solution in which the concentration of X+ is1.50×10−3M ? The pKa of acetic acid is4.76.

Express your answer numerically. Answer is not2.46!
