why should the spatula used for spooning solid chemicals from a reagent bottle be clean and dry?
Answers
Answer:
If it's not clean and dry, you will contaminate the reagent. I was always taught never to even put anything into a reagent bottle. Solid chemicals should be shaken out a little at a time into a weighing boat. Never pour the excess back into the bottle.
A contaminated reagent bottle can give errors to the others that use it, sometimes for years down the road if it's not a commonly used chemical.

Answer:
The spatula used for spooning solid chemicals from a reagent bottle should be clean and dry to avoid contamination of reagents.
Explanation:
A spatula is a flat, broad, flexible blade used to mix or spread the materials. It’s important to keep spatulas clean to help exhibit the spreading of bacteria to food. It is thus very important to wash them thoroughly after using them with raw food, because they could spread bacteria to other food.
Regular cleaning of spatula helps avoiding any unnecessary particle to react with the reagent like, dust, mites, moisture etc.
