Final answer:
A strong acid with a pH of 5.982 has a concentration of H3O+ ions of approximately 1.789 M.option c.
Step-by-step explanation:
A strong acid with a pH of 5.982 means that the concentration of hydronium ions (H3O+) is greater than 1.0 x 10-7 M. The pH scale is a logarithmic scale, so we can calculate the concentration by taking the antilog of the negative pH value. In this case, the concentration of H3O+ ions is 1.0 x 10-5.982 M, which is approximately 1.789 M.
To find the concentration of H₃O+ ions in a solution with a pH of 5.982, we use the formula pH = -log[H₃O+]. Therefore, the concentration of H₃O+ is 10-pH or 10-5.982. Calculating this, we get a concentration close to 1.03 × 10-6 M. Hence the correct answer is D. 1.030× 10-6 M.
