How would you prepare a liter of 10% Ammonia Solution from a Strong Ammonia Solution<\/p>\n\n\n\n

The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n

To prepare 1 liter (1000 mL) of a 10% ammonia solution<\/strong> from a concentrated (strong) ammonia solution<\/strong>, you need to perform a dilution<\/strong> using the formula:<\/p>\n\n\n\n

\n

C\u2081V\u2081 = C\u2082V\u2082<\/strong><\/p>\n<\/blockquote>\n\n\n\n

Where:<\/p>\n\n\n\n

    \n
  • C\u2081<\/strong> = concentration of the strong ammonia solution (e.g., 28%)<\/li>\n\n\n\n
  • V\u2081<\/strong> = volume of strong ammonia needed (what we want to find)<\/li>\n\n\n\n
  • C\u2082<\/strong> = desired concentration (10%)<\/li>\n\n\n\n
  • V\u2082<\/strong> = final volume (1000 mL)<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    Step-by-Step Solution:<\/h3>\n\n\n\n

    Assume your strong ammonia solution is 28% w\/v<\/strong> (a common concentration for commercial ammonia).<\/p>\n\n\n\n

    Use the dilution formula:<\/p>\n\n\n\n

    \n

    (28%) \u00d7 V\u2081 = (10%) \u00d7 1000 mL<\/strong><\/p>\n<\/blockquote>\n\n\n\n

    Solve for V\u2081:<\/p>\n\n\n\n

    \n

    V\u2081 = (10 \u00d7 1000) \u00f7 28
    V\u2081 \u2248 357.14 mL<\/strong><\/p>\n<\/blockquote>\n\n\n\n

    This means you need 357.14 mL of the 28% ammonia solution<\/strong>, and you dilute it with enough distilled water to make the total volume 1000 mL<\/strong>.<\/p>\n\n\n\n

    \n\n\n\n

    Final Procedure:<\/h3>\n\n\n\n
      \n
    1. Wear safety gear<\/strong> (gloves, goggles, lab coat) \u2013 ammonia fumes are irritating.<\/li>\n\n\n\n
    2. Measure 357.14 mL<\/strong> of 28% strong ammonia solution using a graduated cylinder in a fume hood.<\/li>\n\n\n\n
    3. Pour it into a 1-liter volumetric flask<\/strong> (or other appropriate container).<\/li>\n\n\n\n
    4. Add distilled water gradually<\/strong>, mixing gently.<\/li>\n\n\n\n
    5. Fill to the 1000 mL mark<\/strong> with distilled water.<\/li>\n\n\n\n
    6. Mix thoroughly by inverting the flask or stirring.<\/li>\n<\/ol>\n\n\n\n
      \n\n\n\n

      Explanation (300 Words):<\/h3>\n\n\n\n

      Preparing a specific concentration of a solution from a more concentrated stock requires dilution, a fundamental concept in chemistry. The dilution equation C\u2081V\u2081 = C\u2082V\u2082<\/strong> ensures that the amount of solute remains constant before and after dilution, while only the solvent volume changes.<\/p>\n\n\n\n

      In this case, we want to make 1 liter of a 10% ammonia solution. Assuming the strong ammonia is 28% by weight (a common lab stock), we calculate that 357.14 mL of this concentrated solution contains enough ammonia to give us a 10% solution once diluted to 1 liter.<\/p>\n\n\n\n

      It\u2019s essential to add ammonia to water<\/strong>, not the other way around, to reduce the risk of splashing or generating too much vapor. Since ammonia is volatile and has a strong, pungent odor, all work should be done in a well-ventilated area or under a fume hood.<\/p>\n\n\n\n

      This process is a practical example of solution preparation, commonly used in laboratory and industrial settings. Understanding it helps ensure accurate concentrations in chemical reactions, biological experiments, or cleaning formulations.<\/p>\n","protected":false},"excerpt":{"rendered":"
