A sample of grape juice has a hydroxide ion concentration of 1.4 x 10-10 M. Is the grape juice more or less
acidic than a sample of orange juice that has a hydronium ion concentration of 1.8 x 104 M?
To compare the acidity of the orange juice and grape juice, compare the hydronium ion concentrations
and/or pH values of the two solutions.
How does the acidity of a solution vary with hydronium ion concentration and pH?
A. Acidity increases as the hydronium ion concentration increases and the pH increases.
B. Acidity increases as the hydronium ion concentration decreases and the pH increases.
C. Acidity increases as the hydronium ion concentration increases and the pH decreases.
D. Acidity increases as the hydronium ion concentration decreases and the pH decreases.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
