Question

A 0.1 N solution of sodium bicarbonate has a pH value of:
A. 5.6
B. 7.0
C. 8.4
D. 4.0

Answer 1

Hint: Sodium bicarbonate is comprehensively utilized as physiological support in cell culture applications. The pKa for bicarbonate <-> carbonic corrosive response is 6.4 The pKa for bicarbonate <-> carbonate response is 10.3.

Complete step by step answer:
Sodium bicarbonate has been utilized:
• As a segment of ox-like undeveloped organism culture framework during in vitro development, treatment, and culture (IVMFC)
• as a segment of a 1:1 combination of Dulbecco′s changed Eagle′s medium and Ham′s supplement blend F-12 during the way of life of ox-like microvascular endothelial cells
• As a part of ITS (insulin transferrin and selenite) medium utilized during the segregation of dopamine neurons from human early-stage immature microorganisms
• As a segment of the medium utilized for cell culture of human undeveloped kidney cell
• As a segment of Beltsville defrosting arrangement utilized for the weakening of semen
In science, pH is a scale used to determine the sharpness or basicity of a watery arrangement. Acidic arrangements are estimated to have lower pH esteems than fundamental or antacid arrangements. The pH scale is logarithmic and conversely shows the convergence of hydrogen particles in the arrangement.

So, the correct answer is Option C.

Note: Sodium Bicarbonate is the monosodium salt of carbonic corrosive with alkalinizing and electrolyte substitution properties. Upon separation, sodium bicarbonate structures sodium and bicarbonate particles.
