Question

A student was given four unknown solutions each was checked for conductivity and tested with phenolphthalein the results below

Based on data in table which unknown solution could be 0.1M NaOH

Answer 1

The solution which could be with 0.1 M NaOH is solution "C"

Step-by-step explanation:

• I have attached the snapshot of the table for the reference.
• Based on the data from the table, the solution which could be in the 0.1 M of NaOH will be the solution "c" the conductivity is good and the colour with the Phenolphthalein..
• Since the NaOH pH value is always greater than seven.
• And the chemical solution NaOH is based in nature when it is dissolved in nature separates into Na+ and OH- ions.
• NaOH is always a strong base because it completely divides in water to yield hydroxide ions.
