CaCO3 + 2HCl = CO2 + H2O + CaCl2 How many moles of carbon dioxide gas (CO2) will be produced when the antiacid and your stomach acid react? First you need to calculate the total number of moles of HCl in your stomach (Remember that the volume is 500 mL and use the round up number of the pH question).   The antacid is CaCO3 and the stomach acid is 2HCl.

pka=pH halfway to the equivalence point. what is the equivalence point volume? it says to do so by locating the inflection point of the curve. but i'm not sure what the inflection point of the curve is. it says: using a ruler, draw a vertical line that crosses the inflection point and extend this line so it crosses the horizontal axis (use vertical minor gridlines to guide vertical ruler) to find volume base at the equivalence point.

Lola and Richie were tasked to analyze the acidity of a 10.0-mL fermented milk sample diluted with water in a 250-mL volumetric flask. Mola obtained a 15.0-mL aliquot of this solution, diluted it to 50.0 mL, and then titrated this diluted sample. Titration data were given to Rity and she found out that the 50.0-mL sample contains 0.21 mmol of lactic acid. MW: Lactic Acid (90.08)1.What is the lactic acid concentration (in M) of the titrated sample?2. Determine the lactic acid content (in M) of the 10.0-mL fermented milk sample.3. What is the lactic acid concentration (in %w/v) of the 10.0-mL fermented milk sample?
