(30 Points) You need to produce a buffer solution that has a pH of 5.02. You already have a solution that contains 10. mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this solution? The pKa of acetic acid is 4.74. Express your answer numerically in millimoles

as a chemist for an agricultural products company you have just developed a new herbicideherbigon 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 950106 although the formula of this new chemical is a trade secret it can be revealed that the formula for herbigon is x acetate
