What is the principle of bromocresol purple in albumin test?

Bromocresol purple is a pH indicator dye that changes color based on the pH of a solution. In an albumin test, bromocresol purple is used to detect the presence of albumin in urine or serum by changing color from yellow to purple in the presence of albumin. This color change occurs because albumin binds to the dye molecule, causing a shift in pH that results in the color change.

What color range did the substance show when tested with the indicator paper?

Indicator paper is a common name for litmus paper. Litmus paper tests pH. The color range is red to purple, when red is very acidic (pH of 1) and purple is very basic (pH of 14). In between the spectrum are the other pH values. Green is neutral (a pH of 7). Yellow and orange are acids also, ranging from a pH of 2-6. Teal and blue are bases, with pH ranging from 8-13. Hope this helps!
