The pH of a buffer that consists of 1.3 M sodium phenolate (C₆H₅ONa) and 1.2 M phenol (C₆H₅OH) (pKₐ of phenol = 10.00) is 9.82. As

pH = 10 + log ([1.2]/[1.8]) = 9.82.

<h3>What is sodium phenolate?</h3>

An organic chemical with the formula NaOC6H5 is sodium phenoxide. It is a crystalline white substance. The conjugate base of phenol is its anion, phenoxide, sometimes referred to as phenolate. It serves as a base for several other chemical substances, including aryl ethers. The solid form of sodium phenolate is a white to reddish-tinted solid that resembles crystalline rods. They are used in chemical synthesis and as an antiseptic. It performs a cleansing function. Typically, it dissolves in water. The resultant solutions have pH values higher than 7.0 and contain moderate amounts of hydroxide ions. To neutralize acids, they respond as bases.

KonstantinChe [14]

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine: TRUE

<h3>What is the book value?</h3>
  • Book value is the worth of an asset based on its balance sheet account balance in accounting.
  • The value of an asset is determined by subtracting the asset's original cost from any depreciation, amortization, or impairment expenses.
  • Traditionally, a company's book value is equal to its total assets minus intangible assets and liabilities.
  • In practice, however, depending on the source of the computation, book value may include either goodwill or intangible assets, or both.
  • The value inherent in its employees, which is part of a company's intellectual capital, is always overlooked.
  • When intangible assets and goodwill are specifically omitted, the indicator is frequently defined as "tangible book value."

Therefore, the statement "the book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine" is TRUE.
