Turmeric contains pigments called curcuminoids, which change color at different pH levels. In an alkaline environment, the curcuminoids tend to turn a more vibrant red or pink color, due to a change in their chemical structure. This color change is reversible and is often used as an indicator in laboratory experiments.

Starch reaction with iodine at room temperature in neutral acidic alkaline medium which colour is form?
I don't know about acidic or alkaline reactions, but in neutral conditions the reaction of iodine with starch is a dark purple color
What is alkaline medium?
An alkaline medium is a solution that has a higher pH level than 7. It contains more hydroxide ions (OH-) than hydrogen ions (H+). Alkaline mediums are commonly used in various chemical reactions and industrial processes.
How are acid and alkaline products typically detected in a culture medium?
Acid and alkaline products in a culture medium can be detected using pH indicators that change color based on the acidity or alkalinity of the medium. pH strips or pH meters are commonly used to measure the pH levels of the medium and determine the presence of acid or alkaline products. Additionally, microbial growth patterns and metabolic byproducts can also indicate the presence of acid or alkaline substances in the culture medium.

What is alkaline reversion?
Alkaline reversion is a condition in which the medium turns yellow during the first part of the incubation period and then changes to red later due to increased alkalinity by ammonia produced as proteins degrade.
Purpose of the phenol red in the medium?
Phenol red in the medium is a pH indicator that changes color based on the pH of the solution. It helps to monitor the pH levels of the medium during cell culture experiments. Changes in color indicate changes in pH, allowing researchers to adjust the conditions accordingly.
Colour of shigella in DCA medium?
The color of shigella in the DCA medium is straw or pink.
Why pepsin required an acidic medium to break down protein?
because Pepsin is only active in an acid medium and is destroyed in an alkaline and neutral medium at room temperature and below
What is the equivalent weight of potassium permanganate in alkaline medium?
The equivalent weight of potassium permanganate in alkaline medium is 31.6 g/mol. This value takes into account the reduction of permanganate ions to manganese dioxide in alkaline conditions, resulting in a different equivalent weight compared to acidic conditions.
Colour of salmonella in DCA medium?
The color of salmonella in DCA medium is light to dark pink.
