1. choose two of the acids listed, one monoprotic, the other diprotic. write the reactions that occur when each of them react with a solution of naoh. 2. to standardize a solution of naoh, one uses a primary standard called potassium hydrogen phthalate (khp for short). it is a monoprotic acid that can be obtained extremely pure and dried to a constant weight. it has a molar mass of 204.33 g/mol. suppose you weigh out 0.556 g of khp and dissolve it in water. it requires 14.48 ml of naoh solution to reach the endpoint. what is the concentration of the naoh solution? 3. the naoh solution from #2 above is used to titrate a diprotic acid solution of unknown concentration. 25.00 ml of the acid solution requires 26.54 ml of naoh solution. what is the concentration of the acid solution?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
