1. To make a buffer using NH4OH, you must add

a. a neutal salt
b. you can't use it to make a buffer
c. nothing
d. its salt

2. Acidosis is a condition where the body fluids are too acidic. If someone with acidosis uses a lot of salt on their food,
a. the excess sodium ions will tend to raise the pH
b. the excess sodium ions will tend to lower the pH
c. the excess chloride will change the pH
d. it won't directly affect their pH

#1. For a weak base, such as NH3, you want to add a salt of the weak base such as NH4Cl.

For #2 I don't know enough about acidosis to be comfortable in answering the question. Go to Google. There are a plethora of articles on the net where you can find that information.

1. so it D?

2. Acidosis is when your blood pH drops below 7.35 and becomes too acidic. Losing too much water from your body can increase blood pH. This happens because you also lose some blood electrolytes — salts and minerals — with water loss.

Yes. #1 is D.

To answer these questions, we need to understand the concepts of buffer solutions and the effects of salts on pH.

1. To make a buffer using NH4OH, you must add:
To make a buffer solution using NH4OH, you typically add its conjugate acid, which is NH4+ (ammonium ion). The addition of NH4+ and NH4OH creates an equilibrium between the weak acid (NH4+) and the weak base (NH4OH), which helps in maintaining the pH of the solution.

Therefore, the correct answer would be d. its salt.

2. Acidosis is a condition where the body fluids are too acidic. If someone with acidosis uses a lot of salt on their food:
Excess sodium ions from the salt intake won't directly affect the pH of body fluids. Sodium ions (Na+) are neutral and do not contribute to the acidity or alkalinity of a solution.

Therefore, the correct answer would be d. it won't directly affect their pH.
