f
Due to limited sample quantity for dissolvable tobacco, pH measurements were made by measuring 1.0000 ± 0.0005 g of tobacco in 10 mL deionized distilled water and total moisture content was accurately weighed to 1.5000 ± 0.0005 g. Measurements of pH in 1.00 g in 10 mL deionized distilled water were found to be statistically equivalent to 2.00 g in 20 mL deionized distilled water.
