4 0

Answer:

pH of buffer solution is 7.0

Initial pH of Weak acid is 3.27

Final pH of weak acid is 3.07

Amount of NaOH added is 1ml

Explanation:

Titration is a process in which acid and base are introduced together until a neutral solution is achieved whose pH value is near to buffer solution which is 7.0, the pH value for acid is below 7 while pH value for base is above 7.

Solid calcium hydroxide is dissolved in water until the pH of the solution is 10.44. Determine the concentration of the calcium
Orlov [11]

Answer:

1.38x10⁻⁴ M

Explanation:

First, we <u>calculate the pOH of the solution</u>, using the <em>given pH</em>:

  • pOH = 14 - pH
  • pOH = 14 - 10.44
  • pOH = 3.56

Now we <u>calculate the concentration of OH⁻</u>, using<em> the pOH</em>:

  • pOH = -log[OH⁻]
  • [OH⁻] = 10^{-pOH} = 2.75x10⁻⁴ M

Following the reaction Ca(OH)₂ → Ca⁺² + 2OH⁻, we divide [OH⁻] by 2 to calculate [Ca(OH)₂]:

  • [Ca(OH)₂] = 2.75x10⁻⁴ M / 2
  • [Ca(OH)₂] = 1.38x10⁻⁴ M

When a piece of metal A is placed in a solution containing ions of metal B, metal B plates out on the piece of A.(a) Which metal
zmey [24]

While metal B is being reduced from an ion to a solid metal, metal A is being oxidized.

Metal A is being displaced because, through oxidation, it transforms from a solid metal to ions in a solution.

What is Oxidation ?

Redox reactions include a change in the oxidation state of the substrate. Loss of electrons or a rise in an element's oxidation state are both considered to be oxidation.

Gaining electrons or lowering the oxidation state of an element or its constituent atoms are both examples of reduction.

In general, the term "reduction" refers to a reaction in which a chemical receives additional electrons; the compound that gets electrons is referred to as being reduced. We can think of the transformation of a ketone or an aldehyde into an alcohol as a two-electron reduction because hydride can be thought of as a proton plus two electrons.

So finally we can say that Metal A is being oxidized.
