6. a) Define the term pH

pH is a measurement of the acidity/basicity of a solution based on the hydrogen ion concentration.

The pH has a scale from 0 to 14. A solution with a pH of 7 is said to be neutral (neither acidic nor basic). These solutions have an equal concentration of H⁺ and OH⁻ ions. A pH below 7 is acidic (H⁺ > OH⁻) and a pH above 7 is basic (H⁺ < OH⁻).

The equation used to calculate the pH is:

pH = -log[H⁺]

the solar system used to have much dust particles option no d

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
