Objective

Making stock solutions of malachite green in water for lab tomorrow.

Description

  1. Target concentrations
    1. 50 g of 100 ppm malachite green in water
      1. []ppm = massMG/masstotal*1x106
      2. 100 ppm = massMG/50 g*1x106
      3. massMG = 5.00 mgMG
    2. 50 g of 25 ppm malachite green in water
      1. []ppm = massMG/masstotal*1x106
      2. 25 ppm = massMG/50 g*1x106
      3. massMG = 1.25 mgMG

Data

  1. Actual solutions made
    1. Stock 1
      1. 3.06 mg of malachite green
      2. 48.4632 g total after addition of water
      3. 63.1 ppm MG
    2. Stock 2
      1. 1.29 g of malachite green
      2. 48.1828 g total after addition of water
      3. 26.8 ppm MG
