Pre-vaporization formulation for controlling acidity in an e-vaping device

An e-vaping device, comprising:

• a cartomizer including a reservoir holding a pre-vaporization formulation, a mouth piece and a heater configured to heat the pre-vaporization formulation;
• and
• a power supply section removably connected to the cartomizer via a connector and including a sensor housed in a housing, a sensor holder holding the sensor, and a power source disposed in the power supply section and configured to supply power to the heater;
• wherein the pre-vaporization formulation includes:
• a vapor former;
• nicotine;
• nicotine bitartrate in a concentration of about 0.5% to about 2%;
• and
• a combination of acids;
• wherein a pH of the pre-vaporization formulation is between about 4 and about 6, and
• wherein the combination of acids includes formic acid, oxalic acid, glycolic acid, acetic acid, isovaleric acid, valeric acid, propionic acid, octanoic acid, lactic acid, sorbic acid, malic acid, tartaric acid, succinic acid, citric acid, benzoic acid, oleic acid, aconitic acid, butyric acid, cinnamic acid, decanoic acid, 3,7-dimethyl-6-octenoic acid, 1-glutamic acid, heptanoic acid, hexanoic acid, 3-hexenoic acid, trans-2-hexenoic acid, isobutyric acid, lauric acid, 2-methylbutyric acid, 2-methylvaleric acid, myristic acid, nonanoic acid, palmitic acid, 4-pentenoic acid, phenylacetic acid, 3-phenylpropionic acid, hydrochloric acid, phosphoric acid and sulfuric acid.
