When bleach reacts with fabric dye, there is a chemical change. what kind of change happens to the fabric? how could you use the physical properties of melting point and boiling point to identify a substance?

A. Bleach

The bleach reacts with the coloured substances in the fabric and converts them into colourless substances. This is a chemical change.

B. Identification of a substance

Find your compound in a list that gives the melting and boiling points of various compounds.

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.
