Help SN Purity Test Questions

[qwe78978213]

1. I'm not familiar with English, so I'm using a translation tool.
2. I purchased a water test kit for the SN purity test and conducted an experiment, but the test kit didn't show any reaction.
3. Was the kit I purchased not suitable for the test? If so, what kit would be suitable?

If its actually Nitrite (use distilled water for tests) it'll be very light peach/pink, or purple depends on how much you use to test

Is it normal that there is no reaction in the kit after dissolving 30g of SN in 200ml of water?

It should react and show at least iron and or hardness. it'll take a few seconds for the strip to work tho
