Procedure for titrating an acid against a standard solution of naoh. the acid-base indicator, phenolphthalein, is colorless in acidic solution but takes on a pink color in basic solution. how would the volume of standard solution added change if that solution were ba(oh)2(aq) instead of naoh(aq)?

volume of solution required will be half the volume required for NaOH solution.

Explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
