# A beaker contains 38.0 mL of 0.600 M NaOH solution. A few drops of litmus is added to the solution. What is the color of the solution?

The concentration of $O {H}^{-}$ ions in the solution is $0.600 M$.
The pH can be calculated by taking the negative of the logarithm of $0.600$ and subtracting the result from $14.00$:
$p H = 14 - \left(- \log \left(0.600\right)\right) = 13.78$
