what do you think we need to do to help the lake ecosystem? - Answer find out the acids
concentration so we can neutralize it
today we are going to perform a titration what is an acid alkali titration - Answer an analytic
method
what is the primary function of a burette? - Answer dispense solution and an accurate
volume
what should we do to reduce the risk when working with concentrated acids and bases? -
Answer dilute them
why do we use a volumetric flask? - Answer to obtain an accurate and precise volume
in today's titration, we are reacting NaOH and H2SO4. for this reaction, what is the pH at the
equivalence point? - Answer 7
The completion of an acid base titration is represented by the endpoint and equivalence point.
What is the endpoint - Answer Point where the indicator changes color
in the acid alkali titration, the PH changes quickly from 3 to 10 with equivalence point at PH7. If
we use bromothymol blue as an indicator, when will we reach the endpoint? - Answer when
the solution turns from yellow to blue
A standard solution is a solution of accurately known concentration. what is a standard solution
for a titrating sulfuric acid in an acid alkali titration? - Answer an alkaline such as sodium
hydroxide
what is the reaction to describe the neutralization reaction of sulfuric acid and sodium
hydroxide? - Answer H2SO4 + 2NaOH -> Na2SO4 + 2H2O
