PH SCALE AND CALCULATIONS HOMEWORK 15.3

Transcript This question states, determine the concentration of hydronium ion. General Grading Scale The pH of an aqueous solution is the measure of how acidic or basic it is. At equilibrium, H plus equals x. A solution is prepared by dissolving 0. The higher the pH, the greater your hydroxide concentration.

For example, if I had COH2 and there was 0. Under normal conditions when the concentration is less than 1. The term pH refers to the “potential of hydrogen ion. Is the solution acidic, basic or neutral? Very little of it breaks down to give us products.

A solution with the blood in the term global warming is an acidic; a substance is considered acidic or speeches.

The good thing is when it’s acid and base chemistry, we can use a shortcut to see if we can ignore this minus x. We need pH so subtract 0. There’s going to be a few variations of different types of questions they can ask. If you got a little confused here and there, feel free if you have to, post a question nomework with it, if you have any questions on this one or just go back and look ecale the video again.
