Carolyn put drops of Bromothymol Blue (BTB) into a flask, then exhaled bubbles into the flask with a straw for 30 seconds. Use one complete sentence to answer each question.

a. Predict what she would most likely observe happening to the water?

b. Explain what the BTB will indicate (tell us) about the water.

Type the letter that represents the correct location for each particle type below.

Achemist has dissolved a certain substance in water. the chemist knows that more of the substance could be dissolved into the water before it stops dissolving. therefore

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
