Which is the best method for student to identify a solution as an acid or a base?
Testing with pH paper.
we can identify dead microorganisms by they nucleic acid (heritage matter). Nucleic acids are in all viable cells that can maintain even in dead cells. for detection of nucleic acid in a specimen, we must degrade the cell's membrane , extract the nucleic acid, and then detect them by a method such as Polymerase Chain Reaction (PCR).
Could you prepare oxalic acid by adding HCl to a solution of sodium oxalate cooling it to room temp and filtering the resulting mixture?
What type of reaction occurs when a hydrochloric acid solution is mixed with a sodium bicarbonate solution?
How much pure acid should be mixed with 6 gallons of a 50 percent acid solution in order to get an 80 percent acid solution?
Acid solution decreases the pH if it is added to the water, if the solution contains other some basic species, the acid may react with them. an acid (the H+ donor) reacts with a base (H+ acceptor) if the pka (acid)< pka (base). the pH of the solution depends on the type of acid and base, if the acid and base react with each other the pH of the solution depends on the type of…
