Specify which indicator or indicators you would use for the following titrations:
Helen [10]

Answer:

1. Phenolphthalein

2. Phenolphthalein

3. Methyl orange

Explanation:

Different indicators are used by knowing the relative strength of the acid and the bases I.e whether the acid is strong or weak, so also the base.

The following answers are obtainable:

1. Phenolphthalein

We use this indicator for a weak base and a strong acid. Formic acid is a weak organic acid while sodium hydroxide is a strong base

2. Phenolphthalein

We use this indicator because we are dealing with a strong acid and a strong base. Hydrochloric acid is a strong acid while potassium hydroxide is a strong base

3. Methyl orange

This is because we are dealing with a strong acid and a weak base

What is the poH of a 3.67 x 10-5 M OH solution and is it acidic, basic, or neutral?
Anni [7]

Answer:

The pOH is  4, 44 and the solution is basic.

Explanation:

The pOH is a measure of the concentration of OH (hydroxyl) ions in the solution.

The pOH is calculated as :

pOH = -log (OH-)= -log (3.67 x 10-5 )= 4, 44. In this case, the solution is basic.

The p0H scale ranges from values of 0 to 14 (less than 7.0 is basic and greater than 7.0 is acidic, a pH = 7.0 is neutral)

Explain how acids and bases directly or indirectly affect the hydrogen ion concentration of a solution.
ehidna [41]

By taking hydrogen ions, certain bases directly lower the H+ than OH- concentration. Other bases break down to create hydroxide ions, which indirectly lowers the H+ concentration.

<h3>What is the difference between acid and base?</h3>

H+ ion concentration is raised by an acid. A base is a chemical that, in an aqueous solution, produces hydroxide (OH-) ions, gives electrons, and receives protons. A donor of protons is an acid. A proton can enter a base. When dissolved in water, an acidic chemical compound produces a solution that has more H+ ion activity than clean water. A base is an aqueous material that releases hydroxide (OH-) ions, receives protons, or contributes electrons. A donor of protons is an acid. A base is a proton acceptor.

While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Reme
Sophie [7]
I don't get it what does m/s mean its

r= t/d Rate, time, and distance 
time 30min distance 5miles divide 30 = 6 rate is 5 miles every 6min  I think

I don't understand but that's how you calculate rate :P
