Question: What pH value is considered neutral?
Answer:7
Question: What is the molarity of a solution with 1 mole of NaCl in 1 L of water?
Formula:
M = moles ÷ liters
Answer: 1 M
Work:
M = 1 mol ÷ 1 L
M = 1 M
Question: If a solution has a pH of 3, is it acidic or basic?
Work:
pH scale:
0–6 = acidic
7 = neutral
8–14 = basic
Since 3 < 7, it is acidic.
Answer: Acidic
Question: Find the molar mass of CO₂.
Work:
C = 12.01
O = 16.00
12.01 + (2 × 16.00)
12.01 + 32 = 44.01 g/mol
Answer: 44.01 g/mol

300
Question: Find the molarity if 2 moles of KCl are dissolved in 1 L of solution.
Formula:
M = moles ÷ liters
Work:
M = 2 mol ÷ 1 L
M = 2 M
Answer: 2 M
Question: If a solution has a pH of 10, is it acidic or basic?
Work:
10 is greater than 7
Answer: Basic
Question: Find the molar mass of NaCl.
Work:
Na = 22.99
Cl = 35.45
22.99 + 35.45 = 58.44 g/mol
Answer: 58.44 g/mol
Name everybody at your table group first and last name
the correct answer
Question: What ion do acids produce in water?
Answer: H⁺ (hydrogen ion)
Question: What is the molarity of 3 moles of HCl in 2 L of solution?
Formula:
M = moles ÷ liters
Work:
M = 3 mol ÷ 2 L
M = 1.5 M
Answer: 1.5 M
Question: What are the products when HCl reacts with NaOH?
Equation:
HCl + NaOH → NaCl + H₂O
Answer: Sodium chloride and water
Question: Find the molar mass of H₂O.
Work:
H = 1.01
O = 16.00
(2 × 1.01) + 16
2.02 + 16 = 18.02 g/mol
Answer: 18.02 g/mol

Question: What ion do bases produce in water?
Answer: OH⁻ (hydroxide ion)
Question: What is the molarity of 5 moles of NaOH in 5 L of solution?
Formula:
M = moles ÷ liters
Work:
M = 5 mol ÷ 5 L
M = 1 M
Answer: 1 M
Question: What happens to pH when an acid is neutralized by a base?
Answer: The pH moves toward 7 (neutral).
Question: Find the molar mass of NH₃.
Work:
N = 14.01
H = 1.01
14.01 + (3 × 1.01)
14.01 + 3.03 = 17.04 g/mol
Answer: 17.04 g/mol
