1. Write the balanced equation for the reaction between calcium carbonate and hydrochloric acid in water, generating aqueous calcium chloride and liberating carbon dioxide gas. (You will need this for Part 1 of the experiment!) 2. Calculate the concentration of one liter of the resulting calcium chloride solution (assuming you started with 102.7 mg of calcium carbonate) in units of molar and millimolar. Also calculate the concentration in "parts-per-million as CaCO3". (Refer to section 13.5 of your textbook, if needed.)...

the questions below (the 2 worksheet)
_35%. 1:59 AM Introduction In chemistry laboratory, it is sometimes necessary to experimentally determine the concentration of an unknown acid or base solution. A procedure for making this kind of determination is called an acid-base titration. In this laboratory process, a solution of known concentration, called the standard solution, is carefully added to a solution of unknown concentration until the mixture becomes neutral. The neutral point...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
