Compare the rates of change at the different points of the pH scale. a) Does adding two to a pH at one end of the scale (going from a pH of 1 to 3) have the same effect as adding two to a pH at the other end of the scale (going from a pH of 10 to 12)? Support your conclusions. b) Does doubling the pH from 2 to 4 have the same effect has doubling the pH from 5 to 10? Support your conclusions?

In an experiment to determine the amount of aspirin in a tablet, one of the bottles of NaOH used was accidentally left open for 24 hours, which lead to it reacting with carbon dioxide. What will be the effect on the calculated amount of aspirin compared to the actual amount in the tablet and the concentration of the NaOH solution? Calculated amount increases since NaOH concentration will be lower than original. Calculated amount increases since NaOH concentration will be higher than original. Calculated amount decreases since NaOH concentration will be lower than original. Calculated amount decreases since NaOH concentration will be higher than original.

The preparaons of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. acids: 1 mol of NaOH is added to 1.0 L of a 0.7 M HCN bases: solution. other: 0.57 mol of HCl is added to acids: 1.0 L of a solution that is bases: I 1.5M in both HCN and NaCN. other: I Explanation Check 2021 McGraw.HiN Education.
