6. you are given an unknown type of clothing dye. how could you use the procedures in this lab to see if this dye is a mixture?

You could wash it ad use clothing bleach, this should separate the color(s), if they are a mixture. (it worked for me with ink and with dye)

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
