Question

Determine the volume of the liquid in the buret using correct number of significant figures. Step 1 - The numbers in the buret get larger from top to bottom Step 2 - At eye level, notice where the bottom of the meniscus sits Step 3 - Write the big number (long line) at or above the bottom of the meniscus (XX mL) Step 4 - Count the little lines below the big number from Step 3 (XXX mL) Focus on the little line directly above the bottom of the meniscus Step 5 - Guess at the last number (XX XX mL) How far is the bottom of the meniscus from the little line in Step 4? DO NOT INCLUDE UNITS (mL) JUST THE NUMBER

Explanation / Answer

For coloured solution, we read the upper miniscus for burette reading, while for colorless ones, we read lower miniscus to avoid any parallex errors.
So, this being a coloured solution is at 17.7 mL
