The question asks, Consider the following weak acids and their Ka values Acetic acid Ka = 1.8x10^-5 Phosphoric acid Ka = 7.5x10^-3 Hypochlorous acid Ka = 3.5x10^-8 What weak acid-conjugate base buffer system from the acids listed is the best chouce to prepare the following buf...
On the same type of problem as the previous one, it is now asking the pH of 1ml of NaOH plus 50ml water. If i solve for pOH taking .001ml / .051, i get the same number as before, can i just subtract the number from 14 to get pH of the basic solution? 12.29 was what i came up w...
So i need to calculate the pH of 50ml water (de-ionized) with 1 ml of 1M HCl. So the moles of HCl i think is .001 divided by the total amount of solution (.051). I get 0.0196, then i take the negative log of this number and it comes out to 1.71 roughly. Does this sound right? ...
if s''(t)=((-)1/4t^3/2) +8 Then what is s''(16)?
The position s of a point (in feet) is given as a function of time t (in seconds). s = −10 + t − 15t2; t = 8 (a) Find the point's acceleration as a function of t. s''(t)= I know this answer, it is -30 (b) Find the point's acceleration at the ...
