3.	From which substance natural indicators are prepared? Explain any one in detail with procedure.
Answer» $\huge\mathbb\purple{HELLO\:DEAR}$ $\huge\boxed{\texttt{\fcolorbox{Red}{aqua} {ANSWER : }}}$ ⭐⭐⭐⭐ PERFECT ANSWER ⭐⭐⭐⭐ ➡ INTRODUCTION : Natural indicators are generally extracted from natural materials, for example, Litmus is a natural indicator which is extracted from Lichens that belong to the division THALLOPHYTA. ➡ ILLUSTRATIVE EXAMPLE : Let us take an example - Turmeric paper indicator which is a kind of natural indicator. ➡ PROCEDURES OF MAKING : ⃣ Take some turmeric powder. ⃣ Mix it with WATER to make a paste. ⃣ Put this paste on a blotting or filter paper. ⃣ Let dry this paper completely. *⃣ Now cut the dry paper into strips. Thus, the turmeric paper indicator is ready. ➡ TURMERIC PAPER INDICATOR : Turmeric contains a yellow dye. In basic medium, turmeric paper indicator CHANGES its colour to reddish or dark brown colour. We must have seen that if there isna yellow stain on a white cloth, it turns reddish or dark brown when we will wash it with soap. This is because the soap solution is basic in NATURE and it changes the colour of turneric stain to reddish brown colour. ✨✨✨✨ ALWAYS BE BRAINLY ✨✨✨✨
