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 8.10×10−6. 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 2.00×10−3 m ? the pka of acetic acid is 4.76.
