How is hydrogen sulfide demonstrated in KIA medium?
The KIA medium has an iron salt-ferric ammonium citrate- and sodium thio sulfate. The ferric ions bind with the hydrogen sulfide to then form ferrous sulfide, which gives off a black percipitate that can be seen on the media.
What is the pH value of ferric chloride?
The ferric chloride solution is acidic.
PH of potassium citrate?
Potassium citrate is an alkaline salt.
Why is the citrate test carried out on an agar slope rather than a broth?
Background:Simmons' Citrate Agar is a defined, selective medium that tests for an organism's ability to use citrate as a sole carbon source and ammonium ions as the sole nitrogen source.The medium contains citrate, ammonium ions, and other inorganic ions needed for growth.It also contains bromothymol blue, a pH indicator. Bromothymol blue is green at pH below 6.9, and then turns blue at a pH of 7.6 or greater.SO:Sometimes, it is possible to detect growth on the citrate slant without the accompanying color change to blue. This is most likely due to insufficient incubation. Either a combination of blue color and growth or growth alone without the blue color should be scored as a positive for the citrate use test.
What is the pH of FeNO33?
