Talc powder alkalinity can rise due to the presence of impurities or additives that are alkaline in nature. These impurities can increase the pH of the talc powder and make it more alkaline. Additionally, exposure to moisture or other environmental factors may also contribute to the rise in alkalinity of talc powder over time.
If copper powder and iron powder are mixed together, no noticeable reaction will occur as long as they are not exposed to any external factors like heat or moisture. However, if these metals are heated in the presence of oxygen, iron will undergo oxidation and rust, while copper will remain unaffected due to its lower reactivity.
Turmeric powder is commonly used as an indicator. When added to a substance, it turns red in the presence of a base and yellow in the presence of an acid. To test if salt is acidic or basic, mix a small amount of turmeric powder with water and add a pinch of the salt. If the turmeric turns red, the salt is basic; if it turns yellow, the salt is acidic.

by diluting it in water,if precipitation occurs,it shows adulteratiion.or by alkali test.
it is mixed in as a marination or put right in the pot.

Powder microscopy is evaluation/quality control method, used for medicinal plants to study the specific microscopic characters using different staining reagent. Applications in detection of adulterants in sample by performing comparison study using authenticated sample.
