In an acid-base titration, how would you monitor the progress of the experiment and know when it was completed? A. Continue the reaction until you have added an equal volume of acid to the base.
B. Add 1 ml of acid at a time to the base and monitor with pH paper until it is neutral.
C. Use indicator solution which changes color when enough acid is added to react with all the base.
D. Place a thermometer in the flask and continue adding acid until a temperature change is noted.

What is the nature of the ca-cl bond in a molecule of calcium chloride (cacl2) if the electronegativity value of calcium is 1.0 and that of chlorine is 3.16?

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
