想去Tetra的網站問他幾個問題
1.將1.2號試劑及鋅粉依序加入後他說要shake well 20秒(中文說明沒說要搖ㄉ均勻)
有何作用(因為搖了以後看不出有反應而且鋅粉還是沉澱或是已經產生化學反應)
2.將3號試劑也加入後shake gently靜待十分鐘等變色(說明書上寫ㄉ)
問題是我要是用力搖顏色會變淺
昰稍微搖還是用力搖比較正確
英文不太好詞不達意有大大可以幫我改一改貼到該公司網站上嗎

I have a queation in using Tetratest NO3
I followed the tips to finish the measurement .It seemed to be over 100 mg/l. But I shaked it well again for one or two minutes. THe color changed to be close to the scale of 12.5 mg/l
Can you tell me which is more correct?
to wait 10 minutes or to shake well in the last step.
By the way. In the step5- 6,Adding a spoonful of the powder and shaking well 20 seconds seems to change nothing.
Because the powder still exist.
What's the use of the powder.
To shake the solution well causes the value more correct or incorrect?
thank you.
