Endospore Staining . The name "endospore" is suggestive of a spore or seed-like form ( endo - means within). Resting structures formed by some bacteria for survival during adverse environmental conditions ( nutrient limitation or extreme environments).By krista
What is a Stain. A stain is a substance that adheres to a cell, giving the cell color . The presence of color gives the cells significant contrast so are much more visible. Different stains have different affinities for different organisms, or different parts of organismsBy tyne

The Acidic Environment. YEAR 12 CHEMISTRY. ACIDS AND BASES. Acids are compounds that: have a low pH (below 7) taste sour turn blue litmus paper red react with bases to neutralize them and produce salts release H 2 gas in reactions with active metals aqueous solutions conduct electricity
Acidic/Basic Characteristics. Determination of Acids and Bases. Most solutions of acids and bases are clear and colourless. To determine whether a solution is an acid or base an indicator is used. Chemical that changes colour as the concentration H + ( aq ) or OH - ( aq ) ions change
