WebAnswer in scientific notation with appropriate sigfigs. A buffer solution is prepared by combining (1.2x10^1) mL of (2.50x10^-1) molar acetic acid with (1.900x10^1) mL of (2.40x10^-1) molar sodium acetate. What is the concentration of weak acid in this solution? Note: Your answer is assumed to be reduced to the highest power possible. WebPlace a weigh boat on the scale and zero the mass of the weigh boat by pressing the “0/T.” Use your metal spatula to weigh 4 g of sodium acetate. Record the exact mass of the …
WebThe usefulness of this 0.2 M acetate buffer wouldn't be affected if it was diluted to 0.05 M. This is due to the buffer's pH being constant. Although less sodium acetate and acetic acid would be used, the effectiveness would be the same because their ratios would be the same for the 0.05 M and 0.2 M buffers.
