The reaction between NaOH and H₂SO₄ is as follows;
2NaOH + H₂SO₄ ---> Na₂SO₄ + 2H₂O
stoichiometry of base to acid is 2:1
NaOH is a strong acid and H₂SO₄ is a strong acid, therefore complete ionization into their respective ions takes place.
number of acid moles reacted - 0.112 M / 1000 mL/L x 39.1 mL = 0.0044 mol
the number of base moles required for neutralisation = 0.0044 x 2 = 0.0088 mol
Number of NaOH moles in 25.0 mL - 0.0088 mol
Therefore in 1000 mL - 0.0088 mol/ 25.0 mL x 1000 mL/L = 0.352 mol/L
Therefore molarity of NaOH - 0.352 M
Answer:
velocity
Explanation:
The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
2. the cold water sinks deeper into the ocean
Answer:
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.
