Answer to Question #198748 in Inorganic Chemistry for Rhowinne Marie Bar

Question

a titration of potassium hydrogen phthalate required 38.14 mL of NaOH solution to reach an end point detected by phenolphthalen indicator. find the concentration of naoh

Answer 1

$Molarity = moles/litre$

Moles= 38.14/40= 0.9535

Molarity= 0.9535/1000

Molarity= 0.9× 10–³M
