What happens in an acidic solution?
Acidic solution have high concentration of dissociable H+ ions and have low pH.
How do you classify the aqueous solution acidic or basic?
By observing the [H+] ion concentration and [OH-] concentration in the aqueous solution. If the [H+] ion concentration is higher that the [OH-] ion concentration, it is acidic. Vice Versa for basic.
What is the calibration line in a spectrophotometer used for?
To determine the concentration of a solution. Since the absorption of that solution is directly proportional to the concentration, the concentration of the solution can be determined.
What a substance with a higher concentration of H3O ions?
An acidic solution
If the hydrogen ion concentration of a solution is 10-10M is the solution acidic alkaline or neutral?
Alkaline

What happens to the number of hydrogen ions if a solution becomes more acidic?
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.
What a substance with a higher concentration of H3O ions?
An acidic solution
Why the acidic character increases with the decrease in pH?
The acidic character increases with decrease in pH because the pH and acidity are both dependent on the hydrogen ion concentration, with pH being the negative log of the hydrogen concentration. So, at the concentration of H+ increases, the negative log of the H+ concentration decreases.
If the hydrogen ion concentration of a solution is 10-10M is the solution acidic alkaline or neutral?
Alkaline
What does it mean to have a high concentration of H plus ions?
That you have an acidic solution.
What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
Acidic
Is hydronium ion acidic?
Yes, in fact an acidic solution is, by definition, one where the hydronium ion concentration is higher than the hydroxide ion concentration.
What has more hydrogen ions acidic or basic solutions?
A hydrogen ion is just a proton, H+. The pH of a solution depends on proton concentration, pH = -log of H+ concentration. Therefore, the greater the number of protons present in solution, the lower the pH number, and the more acidic the solution.
What is true about the relative concentrations of hydronium and hydroxide ions in an acid solution?
In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
