Consider the temperature change, together with the volume and concentration of the acid and base, noted in the HAZMAT team's response regulation information(50mL 1M HCl,50mL 1M NaOH,change in temp = 6.7C) . Predict how each of the following variations would affect the observed temperature change. Explain your predictions.
(a) using 100 mL 1M hydrochloric acid and 100mL 1M sodium hydroxide
(b) using 50 mL 2M hydrochloric acid and 50 mL 2M sodium hydroxide
(c) using 25 mL 1M hydrochloric acid and 75 mL 1M sodium hydroxide
(d) using 25 mL 1M sulfuric acid and 75 mL 1M sodium hydroxide
an acetic acid solution of 2.87 pH is titrated with 1.5 mL of bromocresol green. When the color changes to light green, the pH is 3.95. The final color of the solution is dark blue.
