Me i bge ! acids: are generally proton donors produce h+ ions in solution are electron pair acceptors may include all of these characteristics milk is only slightly acidic. the ph of milk is closest to: 2 4 6 8 if the quantity of h3o+ ions in a solution is equal to the quantity of oh− ions, then the ph value would be closest to: 1 4 7 11 a solution has a [oh−] of 1 x 10−9. what is the poh of this solution? 5 7 9 12 when choosing a suitable indicator for a titration between a strong acid and a weak base, the indicator should change color in the ph range of: exactly 7 less than 7 (slightly acidic) greater than 7 (slightly basic) near 14 (very basic) oxidation numbers can be used to identify the element that is being oxidized and the element that is being reduced in a redox equation. true false
