What does yeehaw mean?
Country expression of excitement, similar to yippee!, oh boy!, hurray!
Is the concentration of H plus in solution given the OH equals 2.54 x 10-4?
[H+] = Kw / [OH-] = 1.0*10-14 / 2.5*10-4 = 4.0*10-11 mol/L
What is the h3O concentration in 0.45 m hcn ka of hcn 4.0 10-10?
HCN + H20 => CN- + H3O+ 0.45 X X Solve for X (4.0*10^-10) = x^2/0.45M x=1.34e-5= [OH] Find pOH= -log of the above number then 14-4.87=pH= 9.13
Which of following is a radical?
OH
Is it double oh seven or zero zero seven?
In the movies, I believe it is universally pronounced double-oh-seven.
How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
Calculate the concentration of OH- in a HCL solution where hydrogen concentration is 1.3M?
Kw=[OH-][H+] 1.0X10^-14=[OH-][1.3] [OH-]=(1.0X10^-14)/(1.3) [OH-]=7.7
What happens when a base dissolve?
It increases the concentration of OH - in a solution.
How does the concentration of OH- ions change if its pH changes from 8 to 13?
As pH increases H+ ions concentration decreases means OH- ions concentration increases . If pH increases from 8 to 13 , OH- ions concentration increases.
What happends to the OH- as the H plus increases?
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
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 does the PH solution of a acid and base depend on?
the H+ concentration and the OH- concentration
What is the OH concentration of sulfuric acid?
That would depend on the concentration of the sulfuric acid.
How is the concentration of hydroxyl ions affected when excess base is dissolved in a solution sodium hydroxide?
The concentration oh hydroxyl ions (OH)- is increased.
What solution has a grater concentration h or OH?
Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater
What ions are in a high concentration in a base?
OH-
What is a mixture that is high in concentration and low in concentration?
A very strong Acid --- or Base-. A pH=7 reading means an equal concentration of H+ and OH-. A pH reading of say 1 shows a very high concentration of H+ with an exceedingly low concentration of OH-.
