What does it mean when bromothymol blue turns blue?
Amniotic fluid
Bromothymol is used in obstetrics for detecting premature rupture of membranes. Amniotic fluid typically has a pH > 7.2, bromothymol will therefore turn blue when brought in contact with fluid leaking from the amnion. As vaginal pH normally is acidic, the blue color indicates the presence of amniotic fluid.
What Colour does bromothymol blue turn in a base?
Bromthymol blue is a weak acid. It can be in acid or base form, depending on the pH of the solution. This reagent is yellow in acidic solutions, blue in basic solutions and green in neutral solution.
Is bromothymol blue an acid or base?
Bromothymol blue is an acidic pH chromoionophore where acid to base change corresponds to its neutral to anionic form, respectively. For this reason it can be electrostatically immobilized on the surface on anion-exchanger resin like Amberlite IRA 401. Solutions of different concentration of the indicator were used.
How does bromothymol blue indicate an acid?
Bromothymol blue (also called BMB) is an indicator dye that turns yellow when an acid is present. Whereas, when carbon dioxide is added to the solution, it produces carbonic acid, which lowers the solution’s pH.
What does pH measure?
pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
What is pH level in human body?
Your body’s pH balance, also referred to as its acid-base balance, is the level of acids and bases in your blood at which your body functions best. A normal blood pH level is 7.40 on a scale of 0 to 14, where 0 is the most acidic and 14 is the most basic. This value can vary slightly in either direction.
What happens if you eat phenolphthalein?
Ingestion: Causes gastrointestinal irritation with nausea, vomiting and diarrhea. Expected to be a low ingestion hazard. Inhalation: May cause respiratory tract irritation. Low hazard for usual industrial handling.
