please show work for question #3
![Section: Objective #12- Students can distinguish between strong and weak acids and bases in
terms of definitions and properties, and perform basic acid base reactions with the stoichiometry.
1. Explain how KCI, HBr, HCN, and C12H22O1 behave differently at the particle level when
they are dissolved in water. You can draw pictures or write reaction if it helps your
еxplanation.
2. Identify each of the following solutions, as acidic, basic, or neutral: (And only for the
ones with "explain", briefly explain your choice)
a HC;H;O2 (ag)
b. A solution with [H;O'] = [OH]
Еxplain:
c. A substance with a pH of 4.5 at 25°C
Еxplain:
d. A covalent compound that ionizes with water and accepts an H* from the water.

3. In the following reactions, identify the conjugate acid-base pairs.
CHO; + H;0 + HC,H;O;+ OH-
HC1O4 + H:O + HsO* + CIO
4. What is the molarity of a NaOH solution if 28.2 ml of a 0.355 M H;SO, solution is
required to neutralize a 25.0-ml sample of the NaOH solution?
2NAOH (aq). + H;sO4 (aq) - NazSO4 (aut 2H;0 (1)
5. Which of the following is the most basic? Show work to support your choice or explain
it.
a Solution with a pOH = 8
b. Solution with [H']= 2.5 x10
c. 0.0030IM HNO: solution
6.
Which of the following combinations would act as buffered solution? Explain your
choice.
a HCl and NaCl
b. НCN and KОCN

For your choice above, which component of the buffered solution consumes added strong
base? Explain.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1f2fc927-9fa0-46e3-98ea-45819a76f1ba%2F028b1fa7-8ad0-4e15-bdf1-5a35e1a27ddc%2Frsapdrf_processed.png&w=3840&q=75)
