What are the [H₃O⁺] and the pH of a buffer that consists of 0.55 M HNO₂ and 0.75 M KNO₂ (Kₐ of HNO₂ = 7.1X10⁻⁴)?
xxTIMURxx [149]

The pH of the buffer that consists of 0.55 M HNO₂ is 3.3, which is acidic.

<h3>What is the common name for 0.55 M HNO₂?</h3>

The common name for 0.55 M HNO₂ is Nitrous acid. Only in solution, the gas phase, and in the form of nitrite salts is nitrous acid, a weak and monoprotic acid, known to science. Amines are converted into diazonium salts using nitrous acid. To produce azo colors, azo coupling processes use the resultant diazonium salts as reagents. A nitrogen oxoacid is a nitrous acid. It is a nitrite's conjugate acid. To treat cyanide poisoning, sodium thiosulfate is combined intravenously with nitrous acid (as sodium nitrite).

The specific heat of aluminum is 0.900 j/g•°
SIZIF [17.4K]
To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
                                    H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
                                    H = (30.0 g)(0.90 J/gC)(75 - 25)
                                          H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
