Problem- For the standardization of the NaOH solution , the endpoint was consistently reproduced to a faint pink color. However , the endpoint for the nitration of the acid solution was consistenly reproduce to a dark pink color. Will the reported molar concentration of the acid solution be too high, too low, or unaffected by the differences in colors of the endpoints. Explain.
Please explain above problem in step by step manner so I can easily understand it
