Q337
The specific gravity of laboratory grade H3PO4 is (in g mL-1)
A.
1.42
B.
1.84
C.
1.19
D.
1.70
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Phosphoric acid is an inorganic compound with the chemical formula H3PO4. It is a colourless, odourless and non-volatile syrupy liquid.The specific gravity of any liquid is the "the ratio of the density of the liquid to the density of water at 4 degrees Celcius". the specific gravity of laboratory grade H3PO4 is 1.70 g/ml.
