What is the concentration of hydronium ions [H₃O⁺] for this healthy person at a blood temperature of 25°C?

/in /by

A healthy individual has a blood pH measured to be 7.40 at 25°C. What is the concentration of hydronium ions [H₃O⁺] for this healthy person at a blood temperature of 25°C? 2. What it the pH of a buffered solution that has an acetic acid concentration of 0.15 Molar CH₃COOH and a sodium acetate concentration of 0.054 Molar NaCH₃COO? 3. What is the pH of a 0.25 Molar sodium hydroxide (NaOH) aqueous solution? 4. Why is the salt sodium chloride NaCl a stable ionic compound which is the product of the acid-base neutralization reaction between hydrogen chloride HCl, hydrochloric acid when hydrogen chloride gas is dissolved in water, and sodium hydroxide NaOH? 5. Why is ammonium cyanide NH₄CN not a stable ionic compound, or not a stable salt, generated by the acid-base reaction of hydrogen cyanide HCN and ammonia NH₃?
