The Acid in Beaker A is (weaker/stronger) and (more/less) dilute
Stronger and more dilute.
Bromothymol blue is a pH indicator which turns yellow in acidic solutions. Which of the following would make the Bromothymol turn yellow
A) pOH=8.5
B) [H+]=1.0x10^-10M
C) [OH-]=1.0x10^-3
D) pH=8.5
A) pOH=8.5
If the pH of a body of water increases from 8 to 10, what has happened to the hydrogen concentration of the water?
The [H+] is 100 times lower.
What acid and base would react to produce CaCO3 and water
Ca(OH)2+H2CO3
True/False: Water can act like and acid or a base. When water behaves like a Bronsted-Lowry acid it accepts an H+ ion and turns into a hydronium ion.
False. The water donates a hydrogen molecules and becomes hydroxide (OH)
True/False: If NaOH is added to a sample of HCl, the equivalence point is when [H+]=[OH-] and the NaOH had completely neutralised the HCl
True
True/False: Arrhenius defined a base as a substance that produces H+ ions when dissolved in water.
False, [OH-]
What is the Correct name of H3P
HydroPhosphoric Acid.
The pH of the solution is a measurement of the concentration of ___ Ions in a solution
