55. Human blood is buffered by carbonic acid and bicarbonate ions. Alkalosis is a condition caused by excess production of bicar- bonate in the blood. A patient's blood plasma has a pH = 7.6 (pKa for H2CO3 at body temperature is 6.1). MISSED THIS? Read Section 18.2; Watch KCV 18.2B, IWE 18.2, 18.3 [HCO3] [H2CO3] a. What is the ratio of in the patient's blood? b. The doctor gives the patient 0.45 g of HCl intravenously to neutralize alkalosis. After treatment, the patient's blood is 0.0156 M in HCO3¯ and 0.0012 M in H2CO3. If the volume of blood in the patient's body is 5.3 L, what is its new pH?
The pK, value for HCN is 9.40. Would a buffer prepared from HCN and KCN with a pH of 11.4 be considered to be an effective buffer? A buffer in which the mole ratio of KCN to HCN is 0.60 has a pH of 9.18. Would this buffer solution have a greater capacity for added acid (H30*) or added base (OH )?
Which of the following titrations result in an acidic solution at the equivalence point? NH 3 titrated with HCl CH 3COOH titrated with KOH LiF titrated with KOH HI titrated with LiOH
Given that the Ka for acetic acid is 1.8 x 10-5. What is the pH of a buffer solution made from 0.20 M sodium acetate and 0.10 M acetic acid?
Consider the following reaction:CH3COOH(aq)+OH−(aq)CH3COO−(aq)+H2O(l) pKa: 4.75 How much 5.60 M NaOH must be added to 420.0 mL of a buffer that is 0.0205 M acetic acid and 0.0260 M sodium acetate to raise the pH to 5.75?
What is the pHpH of a buffer solution containing 8.0×10−2 M HNO2 and 5.0×10−2 M NO2−?
If a small amount of a strong base is added to a buffer made up of a weak acid, HA, and the sodium salt of its conjugate base, NaA, the pH of the buffer solution does not change appreciably because the strong base reacts with A- to give H2O no reaction occurs the strong base reacts with A- to give HA the strong base reacts with HA to give A- rhe Ka of HA has changed
How many of the following three choices are not effective buffers?NaCHO 2/HCHO 2NaH 2PO 4/H 3PO 4NaF/NaOH
Which is true about buffer solutions? -they hold the pH close to the pKa -they contain comparable moles of a weak acid and a strong base - they hold pH constant at pH=7 -they prevent acids and bases from reaching equilibrium -they hold the pH close to the equivalence point pH
A formic acid buffer solution contains 0.18 M HCOOHHCOOH and 0.13 M HCOO−HCOO− . The pKa of formic acid is 3.75. What is the pH of the buffer?
