Question

OADVANCED MATERIAL Making qualitative estimates of pH change e foulumn describes a change in the solution. . Use the fifth column to predict how the change in the solution will change its initial type (check all that apply) solution/ initial component effect of change on change (check one) acidic O pH higher | basic H20, NaOH add HCIO4Hlower neutral acidic basic neutral acidic basic neutral acidic basic neutral O pH the same O pH higher O pH lower O ph the same O pH higher H,0 add KBr cH2O, NaOH add NaCIo O pH lower O pH the same O pH higher ph lower O pH the same add KOH

Explanation / Answer

solution    initial components    initial type    change                        effect of change on
A             H2O, NaOH              basic            add HcLO4           PH lower
B             H2O                     neutral           add KBr                PH the same
C             H2O, NaOH              basic          add NaClO4       PH lower
D             H2O                     neutral       add KOH                            PH higher
