Asample of grape juice has a hydroxide ion concentration of 14 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 10-4 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?
acidity increases as the hydronium ion concentration increases and the ph increases
acidity increases as the hydronium ion concentration decreases and the ph increases.
acidity increases as the hydronium ion concentration increases and the ph decreases.
acidity increases as the hydronium ion concentration decreases and the ph decreases

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
