What is the measure of acidity in terms of hydronium ion concentration?
pH is a measure of the activity of hydroxide (OH-) and hydronium (H3O+) in aqueous solution. Acidic solutions have greater numbers of reactive hydronium ions. Basic solutions have more hydroxide ions and less reactive hydronium ions.
What are the two ions that make up water?
Water is made up primarily of neutral water molecules, H2O. However, these molecules can undergo an autoprotolysis reaction, creating hydronium (H3O+) and hydroxide (OH-) ions. Note that sometimes the hydronium ions are simply represented as H+, but this notation is not strictly correct, as free hydrogen ions do not exist in aqueous solution.
Is it true that in strong acids most of the molecules break up into ions in the solution?
Yes, that is true. Strong acids ionize, in a aqueous solution. It is the released hydrogen ions that make them acids.
When a solution of an acidic reacts with a solution of a base hydronium ions react with hydroxide ions to form?
They form water! H3O+ OH = 2H2O . If you can see, there's four hydrogens, two oxygens. This is just enough to make 2 molecules of water!
A neutral solution has an equal numbe of?
A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.

What ion found in a solution would it make it basic?
A hydroxide ion found in a solution would make it basic. Another name for a hydroxide ion is a hydronium ion. Acids would donate hydrogen ions.
What kind of bond do hydrogen and clorine make?
Though they dissociate into ions in an aqueou solution, a bond between hydrogen and chlorine is covalent.
Why may solutions that contain an ionic solute conduct electricity?
The conductivity of an aqueous solution depends on the presence of free ions. Some solutes do not ionize in water (e.g. sugar) and so do not make a conductive solution. Others partially ionize (e.g. acetic acid) and so make a poorly conductive solution. Still others completely ionize (e.g. table salt) and so make a very conductive solution.
What substance was responsible for the change in pH?
In order to change the pH, one of two ions must be formed. Producing hydronium ions will make the pH more acidic. On the other hand, producing more hydroxide ions will make the solution's pH more basic.
What pH of pka is 5.4?
This question does not make very much sense but it will somewhat be answered. PH is the measurement of a concentration of hydronium ions in a solution. PKA is the measurement of how much is available. If the concentration and pka of a substance is known, the pH can be calculated.
Why do biologist use solutions that are aqueous?
biologist used aqueous solution to perform chemical test as this solution behaves as the medium for chemical reaction and is also the medium of chemical reaction in living beings so that is why biologist use aqueous solution.
What ions are created by the ionization of hydrogen and chlorine atoms that make up hydrochloric acid?
HCl (aq) + H2O (L) ---------> H3O+ (aq) + Cl- (aq)
