Nitrite strips test as per the ppeh:
You'll need:
- Digital scale to weigh 5g of SN
- 2 x one litre bottles of distilled water
- Separate liquid container, like a cup for example.
- 2ml pipette
- Nitrite test strips. Should measure up to 10mg/L. Usually part of an aquarium test kit
The test procedure:
- Use the digital scale to weigh 5g of SN
- Take two cups, pour in 1 liter of distilled water in both the cups
- Pour 10 to 20ml from one of the water cup into the separate container
- Stir the SN in the distilled water in the container until dissolved.
- Return the mixture to the same cup
- Reseal, shake, and then re-open
- Take 2ml from the mixture in the cup using the pipette. (I'll use the dropper that comes with the cannabis oil. It's 1ml. So, I'll use it twice.)
- Add the 2ml mixture to the 2nd cup which contains another 1 liter of distilled water.
- Reseal, shake, and then re-open
- Use the nitrite test strips and the color chart to test.
- If the SN is pure, the color change in the test strip should match the 10mg/L in the color chart
Documented SN strips test with pictures:
1. Prepare 2 cups with
500mL of distilled water each. I didn't find 1L distilled water bottles in nearby stores. So, I recalculated the test based on 2 x 500mL.
2. Weigh
2.5g of SN
3. Dissolve the 2.5g of SN in
cup1. Then, take
1mL from the
cup1 and add it to
cup2.
4. Now, we have 2.5g/500mL or 5g/L in
cup1, and 10mg/L in the
cup2. This picture actually the same as picture 1. Just distilled water. I reused it to explain this step.
5. Use the testing strips to test for Nitrite. We need the concentration of Nitrite in
cup2. But, I tested both for comparison. I think the result is close to 10mg/L. Which is good.
6. Here is a closer look of the testing strip next to the color chart.
If you have mineral water instead of distilled water, Just test the mineral water without SN first. Then do the test with SN and subtract what you got from the first test from the results.
