1.What data is collected in a titration?

2.How would I be able to find what the volume of 0.10M HCl should be needed to titrate .136 g Na2CO3 according to the reaction equation:

Na2CO3(aqueous) +2HCl(aqueous) &#61664; 2NaCl(aqueous) + H2O(liquid) + CO2(gas)

3.How would I determine the density of a solid using water displacement? Can you give me a detailed procedure with steps??

4.What is the density and specific heat (heat capacity) of aluminum, zinc and iron?

a. In Titration, a solution of known concentration (the standard) is added via buret to a solution of unknown concentration until all of the unknown solution is consumed at the Endpoint (aka Equivalence Point or Neutralization Point). Indicator undergoes permanent color change. This volume is the data that is measured in a titration

b. When titrating, practice is necessary to deliver a single drop of solution,
to produce the equivalence point, i.e., neutralization, the point where the indicator changes color permanently. With the help of following calculation, the volume of HCl required can be determined:
