A purple solution in universal indicator indicates an alkaline solution with a pH of 14
pH paper turns blue or purple in alkalis.
The pH 10 solution will turn purple because the purple color is stable over a wide pH range. However, if the purple solution contains an indicator that changes color at different pH values, it may undergo a color change.
Neutral litmus is purple at pH=4,3.

The Ka for metacresol purple is not readily available. The pH range for this indicator is typically around 7.2 to 9.8 where the color transition occurs. At pH 9.0, metacresol purple would likely be predominantly purple, indicating a higher pH level.

Neutral litmus is purple at pH=4,3.
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.
In Purple Power, the pH value refers to the level of acidity or alkalinity in the cleaning solution. pH is a measure that ranges from 0 to 14, with lower values indicating acidity, higher values indicating alkalinity, and a value of 7 being neutral. The pH value of Purple Power can vary depending on the specific formulation of the product.

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.
