Questions & Step-by-Step Solutions

What is the result of mixing equal volumes of 0.1 M HCl and 0.1 M NaOH?
  • Step 1: Understand that HCl is an acid and NaOH is a base.
  • Step 2: Know that when an acid and a base mix, they can neutralize each other.
  • Step 3: Recognize that 0.1 M HCl means there are 0.1 moles of HCl in one liter of solution.
  • Step 4: Similarly, 0.1 M NaOH means there are 0.1 moles of NaOH in one liter of solution.
  • Step 5: When you mix equal volumes of these solutions, the moles of HCl will equal the moles of NaOH.
  • Step 6: The reaction between HCl and NaOH produces water (H2O) and sodium chloride (NaCl).
  • Step 7: Since they neutralize each other completely, the resulting solution will not be acidic or basic.
  • Step 8: The pH of a neutral solution is 7.
