  1. Oct 06,  · Answers. Best Answer: moles NaOH = L x M= a moles HCl needed = V = / = L = mL b moles HNO3 needed = V = / = L = mL c moles HC2H3O2 needed = V = /= L = mL.
  2. a material or substance with a pH lower than 7. Acids have a tart, sour flavor. Many foods are acidic and give different acid profiles to foods. Some examples are citric acid derived from lemons, acetic acid from wine and grapes, and malic acid from apple cider or apple products.
  3. pH calculation - diluted strong acids and bases. In principle, when a strong acid or a strong base produces in solution a concentration of ions H3O+ or OH- greater than M you can just neglect the contribution given to the concentration of these ions (and then to the pH) by the water autoionization .
  4. Volume of hydrochloric acid solution used = cm3 Moles of hydrochloric acid used = x / = Na2CO3 + 2HCl 2NaCl + H2O + CO2 1 mole 2 moles 2 moles 1 mole 1 mole Moles of Na2CO3 used = / 2 = Molar mass of Na2CO3 = g mol-1 Mass of Na2CO3 present in 25 cm3 = x g = g Mass of Na2CO3 present in cm3 = g Mass of .
  5. Calculate the volumes of acid used in the three trials. Show your calculations and record your results below. Trial 1: Volume of HCl mL – mL = mL x 1 L / mL L b. Trial 2: Volume of HCl mL – mL = mL x 1 L / mL L c.
  6. Lecture Acids and Bases IV. Tutorial. 1) When a g sample of NaCl is added to a L saturated solution of PbCl. 2, does the concentration of Pb. 2+ increase, decrease, or stay the same? Justify your answer. Assume that the overall volume of the solution does not change. PbCl. 2(s) Pb 2+ (aq) + 2 Cl-U (aq).
