Part b As a chemist for an agricultural products company, you have just developed a new herbicide,"Herbigon," that you think has the potential to kill weeds effectively. A sparingly soluble salt, Herbigon is dissolved in 1 M acetic acid for technical reasons having to do with its production. You have determined that the solubility product Ksp of Herbigon is 9.00×10-6Although the formula of this new chemical is a trade secret, it can be revealed that the formula for Herbigon is X-acetate (XCH COO, where "X" represents the top-secret cation of the salt). It is this cation that kills weeds. Since it is critical to have Herbigon dissolved (it won't kill weeds as a suspension), you are working on adjusting the pH so Herbigon will be soluble at the concentration needed to kill weeds. What pH must the solution have to yield a solution in which the concentration of X* is 4.00×10-3 M? The pKa of acetic acid is 4.76. Different salts have different solubilities in water.For some salts, the addition of H+ or OH- to thesolution can actually increase its solubility.▼ Part BReview | Constants I Periodic TableAs a chemist for an agricultural products company, you have just developed new herbicide,"Herbigon,"that you think has the potential to kill weeds effectively.

that you think has the potential to kill weeds effectively. A sparingly soluble salt, Herbigon is dissolved in 1

product Ksp of Herbigon is 9.00x10-6
Although the formula of this new chemical is a trade secret, it can 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 have Herbigon dissolved (it won't kill weeds as a suspension), you are working
on adjusting the pH so Herbigon will be soluble at the concentration needed to kill weeds. What pH must
the solution have to yield a solution in which the concentration of X+ is 4.00x10-3 M? The pK₂ of acetic
acid is 4.76.
