What else can I help you with?
The concentration of an acid or base refers to?
False
Is ture or false the hydronium ion concentration of a solution that has a pH of 4.12 is 7.5910-9 M?
True, the hydronium ion concentration of a solution can be calculated using the formula [H3O+] = 10^(-pH). In this case, [H3O+] = 10^(-4.12) ≈ 7.59 x 10^(-5) M or 7.59 x 10^(-9) M.
True or false Tritium is an isotope of hydrogen with 2 neutron?
False. Tritium is an isotope of hydrogen with 2 neutrons.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
Is this statement true or false You can make a concentrated solution more dilute by adding solvent.?
True. A concentrated solution can be made more dilute by adding more solvent, which increases the volume of the solution and decreases the concentration of the solute. This process effectively reduces the ratio of solute to solvent, resulting in a less concentrated solution.
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
True or false As the concentration of a colored solution increases the absorbance value decreases?
Absorbance rises with concentration because there is more material for a given frequency of light to be absorbed in. Your statement is false.
The concentration of an acid or base refers to?
False
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
Is a substance that forms hydrogen ions in water solution a base?
false
Distilled water is about the only completely neutral solution. What is its pH?
Almost anything - its not buffered. (Your first statement is false)
A base is a substance that forms hydrogen ions in a water solution?
This substance is an acid.
Is an acid a substance that produces hydroxide ions in a water solution?
False
True or false The concentration of an acid or base refers to how completely it dissociates in water?
False. The concentration of an acid or base refers to the amount of the acid or base present in a given volume of solution, while the extent of dissociation refers to how completely the acid or base breaks apart into ions in water.
Is ture or false the hydronium ion concentration of a solution that has a pH of 4.12 is 7.5910-9 M?
True, the hydronium ion concentration of a solution can be calculated using the formula [H3O+] = 10^(-pH). In this case, [H3O+] = 10^(-4.12) ≈ 7.59 x 10^(-5) M or 7.59 x 10^(-9) M.
Is it possible to have a concentrated solution of a weak acid or base True or False?
True. It is possible to have a concentrated solution of a weak acid or base, as the concentration of a solution refers to the amount of solute dissolved in a solvent, regardless of the strength of the acid or base. The degree of dissociation may be low, but the concentration can still be high.
PH value of hydrogen peroxide?
scale pH <--- HUH? hehe
