Which term describes a substance that increases the concentration of hydroxide ions in solution?Lewis definition of an acid
Arrhenius definition of a base
Bronsted-Lowry definition of a base
Bronsted-Lowry definition of an acid

Answers

Since the question pertains to hydroxide ions, or OH-, then we can be sure that the answer is a base. All we have to do is differentiate which of the definition is more appropriate. A Bronsted-Lowry base is defined as the substance that accepts a proton. An Arrhenius base is the substance that produces OH- during the acid-base reaction. Hence, the answer is Arrhenius definition base.

its B

Explanation:

If a pH of water is 5.3 then 4.3 is it 1.0 less acidic 1.0 less basic

Answers

The pH of water is 7
5.3 to 4.3 is more acidic. 1 pH is more acidic than 2 pH The base starts at 8.

It would be 1.0 less basic, 1.0 more acidic

When group 2A element from ion they A. lose two proton
B. gain two proton
C. lose two electron
D. gain two electron

Answers

Well, knowing that group 2A elements are metals, and metals lose electrons to gain a full electron shell, we can eliminate B and D. Knowing that these are 2 electrons, that the group 2A element provides to another atom, to form an ion.

The solution is C. Lose 2 electrons.
