Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. species ОН ΙΟ CIO₂ HCOOH HCIO₂ HIO HCOO relative pH of 0.1 M aqueous solution (Choose one) 7 (Choose one) 2 1 (lowest) (Choose one) (Choose one) X Ś ? 00. 18 Ar

Los Angeles has water regulations that requires any wastewater poured down the drain to be between pH = 4.5 and pH = 9.0. In lab, Dr. Smith is feeling lazy and decides to pour waste down the drain instead of going through the appropriate procedure for disposal of chemical waste. The waste contained your 0.250 M solution of HCl. Does this wastewater comply with the Los Angeles water standards? Hint: Recall that strong acids completely dissociate. HCl → H+ + Cl- How is [H+] related to the concentration of the HCl solution? a)No, this solution has pH below the safe range. b)Yes, this solution has pH within the safe range. c)No, this solution has pH above the safe range. d)The pH will depend on the volume (liters) of solution.

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.
