Determine the ph of a 0.00598 m hclo4 solution. 1.777 6.434 7.566 2.223 3.558

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

A solution whose value is different by n has a difference in the concentration of H ions of 10ⁿ.

0.00598 M HClO₄ solution

HClO₄ is a strong ionized acid:

HClO₄ ---> H⁺ + CLO₄⁻

produces 1 H⁺ ion so it has acid valence 1

So we use a strong acid formula to find the pH

[H⁺] = a. M (a = acid valence, M = acid concentration)

[H⁺] = 1. 0.00598

[H⁺] = 5.98 .10⁻³

pH = - log [H⁺]

pH = - log 5.98 .10⁻³

pH = 3- log 5.98

pH = 2,223

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
