If 0.8675 g of KHP requires 24.56 mL of an NaOH solution to reach the equivalence

ValentinkaMS [17]

Answer:

$M_{base}=0.173M$

Explanation:

Hello there!

In this case, since the titration of acids like KHP with bases like NaOH are performed in a 1:1 mole ratio, it is possible for us to know that their moles are the same at the equivalence point, and the concentration, volume and moles are related as follows:

$n_{acid}=M_{base}V_{base}$

Thus, by solving for the volume of the base as NaOH, we obtain:

$M_{base}=\frac{n_{acid}}{V_{base}} \\\\M_{base}=\frac{0.8675g*\frac{1mol}{204.22g} }{0.02456L} \\\\M_{base}=0.173M$

Best regards!

Which reaction below represents a balanced, single replacement chemical reaction?

kenny6666 [7]

The balanced chemcial equation is B. So to do single, we need to look at where would Li stand on the metals chart (For my class we have a chart to see which element is the highest on the metals chart) . So since Li is higher, F needs to go with Li, leaving Ba alone.

I hope this helps you!
