Acids and Bases Basics
This ion is produced by acids in water.
What is H+
A Brønsted-Lowry acid does this.
What is donates a proton (H⁺)?
What is the pOH of a solution with pH = 6?
What is 8?
What is the purpose of an indicator in titration?
To show the endpoint/color change.
Name one safety rule for handling acids.
Ans vary
A solution with a pH of 11 is considered this.
What is a base?
Identify the base in: HCl + H₂O → H₃O⁺ + Cl⁻
What is H₂O?
Is a solution with pOH 2 acidic or basic?
What is basic?
What was Mrs. Shepherd's very first job?
What is a McDonald's cashier?
Convert 55.0 mL to liters.
What is 0.0550 L?
Name one property of bases.
Slippery feel, bitter taste, turns red litmus paper blue, etc.
Identify the conjugate acid of NH₃.
What is NH₄⁺?
Calculate the pH of a solution with [H⁺] = 1 × 10⁻⁴ M.
What is 4?
HClO4 + NaOH → NaClO4 + H2O
200.0 mL of 0.0753 M sodium hydroxide (NaOH)
0.0748 M perchloric acid (HClO4). How many mL?
What is 201.34 mL
Write the balanced equation for H₂SO₄ + NaOH.
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
What is Mrs. Shepherd's coffee order?
Iced white mocha
In the reaction NH₃ + H₂O ⇌ NH₄⁺ + OH⁻, explain why water acts as an acid.
Water donates H⁺ to NH₃.
What is the concentration of H+ molecules if a solution has a pH of 3.68
What is 2.09x10-4 M?
H2SO4 + 2 LiOH → Li2SO4 + 2 H2O
190.0 mL of 2.1975 M lithium hydroxide (LiOH)
1.28 M sulfuric acid (H2SO4) How many mL?
What is 163 mL?
Which tool measures liquid volume most accurately in titration?
What is a burette?
A student says all acids are dangerous and all bases are harmless. Explain why this statement is incorrect.
Some acids and bases are both dangerous or corrosive; safety depends on concentration and chemical properties, not just whether something is an acid or base.
Explain how conjugate acid-base pairs differ from regular reactants and products.
They differ by one proton.
What is the pH of a solution with a pOH concentration of 1.34x10-8 M?
What is 6.13?
HClO3 + KOH → KClO3 + H2O
180.0 mL potassium hydroxide (KOH) What M?
440.3 mL of 2.35 M chloric acid (HClO3)
What is 5.75 M?
Describe how you could test whether an unknown solution is acidic or basic.
Use indicators, pH paper, conductivity tests, etc.
