The pH meter measure the concentration of the hydrogen(+) ion, and the concentration of Hydroxide(-). Hydrogen is acidic, Hydroxide is basic.

The answer is D.
Fantom [35]3 years ago

Answer: Option (D) is the correct answer.

Explanation:

An electronic device which is used to measure hydrogen ion activity is known as a pH meter.

That is, a pH meter is useful in detecting or knowing the acidity (due to H^{+} ions) or alkalinity (due to OH^{-} ions) of a solution.

Thus, we can conclude that out of the given options it is true about a pH meter that it can be used in any acid-base titration.

Answer:

have the same number of atoms

Explanation:

Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass number (like that for isotopes) . Different mass number will have different number of neutrons.

How many moles of oxygen can be formed from 250 grams of aluminum oxide
Oksanka [162]
2Al₂O₃ = 4Al + 3O₂

M(A₂O₃)=101.96 g/mol
m(Al₂O₃)=250 g

n(O₂)=3m(Al₂O₃)/{2M(Al₂O₃)}

n(O₂)=3*250/{2*101.96}=3.678 mol

Consider a gas in a container that can adjust its volume to maintain constant pressure. Suppose the gas is cooled. What happens
NNADVOKAT [17]

Answer:

The volume will also decrease.

Explanation:

This illustration clearly indicates Boyle's law.

Boyle's law states that the volume of a fixed mass of gas is directly proportional to the absolute temperature, provided the pressure remains constant. Mathematically, it is represented as:

V & T

V = KT

K = V/T

V1/T1 = V2/T2 =... = Vn/Tn

Where:

T1 and T2 are the initial and final temperature respectively, measured in Kelvin.

V1 and V2 are the initial and final volume of the gas respectively.

From the illustration above, the volume is directly proportional to the temperature. This implies that as the temperature increases, the volume will also increase and as the temperature decreases, the volume also will decrease.
