A lab group of students is trying to determine whether a base qualifies as an Arrhenius base or a Bronsted-Lowry base. Which student’s question would be the most useful to explore to help determine this? Student 1 Does the base react with an acid to produce water and a salt? Student 2 Does the base neutralize an acid? Student 3 What is the pOH of the base? Student 4 Does the base accept a proton from the acid? Question 5 options: Student 4 because a Bronsted-Lowry base always accepts a proton from an acid to form a conjugate acid. Student 2 because all bases will neutralize acids. Student 3 because the pOH of the base can be used to calculate the pH of the base. With this information the type of base can be determined. Student 1 because if the base reacts with an acid and produces water and a salt it is a Bronsted-Lowry base.

Student 4, because a Brønsted-Lowry base always accepts a proton from an acid to form a conjugate acid.  

Explanation:

That's the definition of a Brønsted-Lowry base.

Student 2 is wrong. All bases will neutralize acids. That doesn't tell you the type of base.

Student 3 is wrong. The pH of a solution doesn't tell you the type of base.

Student 1 is wrong. Both Arrhenius and Brønsted-Lowry bases react with acids to produce water and a salt.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
