Calculate the mL of acetic acid (0.845 M) and baking soda (assume 0.735 M) that need to be mixed to prepare 240 mL of a 0.25 M buffer of pH 5 and pH 7. I posted my work so far but I got stuck on how to get the volume. How do I proceed based on what I have? Please help! Thank you.
How many moles of sodium acetate should be added to 375 ml of 0.3 M acetic acid in order to prepare a buffer with pH = 4.50? Assume no volume change.
Now they have been tasked to make a 200 ml 0.15 M Tris buffer (pH value is not necessary to answer the questions below!), however, they found that in the chemical cupboard there is only Tris base (Tris-Cl-) powder but the container with weak acid powder is empty. The cupboard does, however, also contain bottles of strong bases and strong acids. i) explain how they can generate a functional buffer although they lack the Tris-HCl weak acid powder. Hint: explain what is necessary to obtain a functional buffer system? Here we do not ask for calculations but for a conceptual account on how the buffer can be made with only the Tris base as starting material. (Less than 150 words) ii) Calculate in grams (g) to three decimals precision the mass of Tris base (Tris-Cl-) powder that is required to generate the desired buffer.
A student needs to prepare a buffer solution with a pH of 4.65. Assuming a pKa of 4.57, how many mL of 0.1 M B- would need to be added to 16.0 mL of 0.1 M HB prepare this buffer? Please include a proper (abbreviated) unit. HINT : Use pH = pKa + log ([B minus]/[HB]) or, if concentrations are the same, pH = pKa + log (Volume of B minus/ Volume of HB)
Chemistry Is possible to make a buffer pH 4 at 1mM using methanesulfonic acid and sodium tartrate? Please explain why
For 480.0 mL of a buffer solution that is 0.160 M in CH3CH2NH2 and 9.00×10−2 M in CH3CH2NH3Cl , calculate the initial pH and the final pH after adding 1.5×10−2 mol of HCl . ( Kb(CH3CH2NH2)=5.6×10−4 .)
A buffer is composed of 0.200 M HC2H3O2 (Ka = 1.8 × 10–5) and 0.250 M NaC2H3O2. What is the pH of the resulting solution after 0.0200 mol of KOH are added to 500.0 mL of the buffer? Assume that the change in volume is negligible. SOLVE USING MOLARITY IN ICE TABLE NOT MOLES Enter your response in pH units to the nearest 0.01.
Chemistry WIll rate/give points thank you!! John is creating a 625 mM HEPES-KOH buffer in 250 mL volume at a pH of 8.0. what volume (in milliliters) of 5 M KOH should you use? Show all steps.
Which of these statements is true? (a) If you add strong acidor base to a buffer, the pH will never change. (b) In orderto do calculations in which strong acid or base is added toa buffer, you only need to use the Henderson–Hasselbalchequation. (c) Strong bases react with strong acids, but not weak acids. (d) If you add a strong acid or base to a buffer, thebuffer’s pKa or pKb will change. (e) In order to do calculationsin which a strong acid or base is added to a buffer, you need tocalculate the amounts of substances from the neutralizationreaction and then equilibrate.
