<span>Mn(HPO4)2 - managanese (II) monohydrogen phosphate ion</span>
Explanation:
It is known that when pH of a substance is more than 7 then the substance is considered basic in nature. When pH of a substance is less than 7 then the substance is considered acidic in nature.
And, when the pH of a substance is equal to 7 then it is considered neutral in nature.
The pH of given substances are as follows.
Coffee = 5.0
Orange Juice = 3.5
Milk = 6.5
Soda pop = 2.5
Battery acid = 1.0
As battery acid as very low pH therefore, it is highly acidic in nature.
Thus, we can conclude that given acids are arranged in increasing order of acidity as follows.
Milk < Coffee < Orange juice < Soda pop < Battery acid
Answer:
B, C, E
Explanation:
What you are trying to do is increase the solute/solvent ratio.
B. Adding more solute increases the value of the numerator, so it increases the ratio.
C. Boiling away some solvent decreases the value of the denominator, so it increases the ratio.
E. Heating the solution so more solute dissolves increases the value of the numerator, so it increases the ratio.
A is wrong. Adding more solvent makes a more dilute solution.
D is wrong. The solvent dissolves the solute.
