acid base help plz?

Question

1All Brønsted-Lowry bases contain the hydroxide ion, OH-.
True
False

2. A solution is prepared by adding 0.10 mol of potassium chloride, KCl, to 1.00 L of water. Which statement about the solution is correct?
The solution is basic.
The solution is neutral.
The solution is acidic.
One needs to know the temperature before any of the above predictions can be made.
The values for Ka and Kb for the species in solution must be known before a prediction can be made

plz show works on number 2 or any explainations, thank you

Answer 1

1. False. By the Bronsted-Lowry definition, a base is a proton acceptor, not a hydroxide donor (which is the Arrhenius definition), so it does not have to have OH- in the formula. For instance, carbonate is a B-L base because it can accept a proton from water to form bicarbonate and hydroxide.

2. The solution is neutral. The salt is the result of the reaction of a strong acid and a strong base (HCl and KOH), therefore neither component has any acid-base properties.

Answer 2

=============================
False - Simply need a proton donor and acceptor so you will have a Hydrogen ion(proton) but not necessarily a hydroxide ion , although hydroxide is common in a n aqueous solution

KCl in water is acidic.
Depending on concentration , in a saturated solution it is at pH 5.8 at Standard temperature of 25 C

Answer 3

interior the lab that I artwork in, we obtain samples to attempt for his or her content of ammonia. We verify it doing an acid/base titration with standardized H2SO4 the information is utilized by making use of engineers to alter the residences of the catalysts being designed.

Answer 4

I only know the first one. It's false because an base doesn't need OH, it can have NH3 or NH4, forgot which one

Answer 5

Homework, huh?
