Which preservatives are used for urine preservation?
Different types of urine preservatives are boric acid, tartaric acid, thymol, clorhexidine/ n-propyl gallate and sulphuric acid.
What is the chemical formula of trypan blue?
what is the chemical formula for thymol blue
Is thymol mercury?
No. You are thinking of thimerosal. Thymol is in thyme and oregano oils.
What colour would thymol blue go if hydrochloric acid was added?
Thymol blue will be yellow at pH < 8
What is thymol blue in acid?
It is Red in Strong Acid like pH 1 or 2 and then it's Yellow
What colour is thymol blue in acid?
It is Red in Strong Acid like pH 1 or 2 and then it's Yellow
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
An indicator that changes its colour around pH value 5 should be used in this titration. Alternatively, instead of Thymol Blue, Methyl Orange or Methyl Red may be used.
What is the absorbance value for thymol?
thymol blue 436, 545 and 595 nm
What colour would a mixture of thymol blue and phenolphthalein go if you added hydrochloric acid?
HCl has a pH of 1 so thymol blue would turn red in this acidic condition. Phenolphthalein is colorless in an acid so what you would see would be red.
In which solution will thymol blue indicator appears blue?
KOH
What substance is used as an acid-base indicator?
Phenolphthalein, Metyl Orange, Methyl Red, Thymol Blue and Bromothymol Blue are some of the commonly used acid-base indicators. The property of such indicators should be the capability of showing a distinct chemical change with respect to a particular pH value.
Which preservatives are used for urine preservation?
Different types of urine preservatives are boric acid, tartaric acid, thymol, clorhexidine/ n-propyl gallate and sulphuric acid.
What is a strong acid pH?
a strong acid is about 1 or 2 possibly in a pH scale and it turns many pH indicators (such as thymol blue, orange IV, methyl orange, methyl red and litmus paper) red.
What is the chemical formula of trypan blue?
what is the chemical formula for thymol blue
What is a substance that changes color when mixed with an acid or base?
acid base indicator or pH indicatorSome examples of acid base indicators are: gentian violet, malachite green, thymol blue, methyl yellow, bromophenol blue, congo red, methyl orange, screened methyl orange, bromocresol green, methyl red, methyl purple, phenolphthalein, indigo carmine, hydrangea flowers, anthocyanin, litmus, red cabbage, and purple cauliflower.
