Consider 25.0 mL of 0.100M HA (HA is a fictional acid), for which Ka=1.00x10^-5, titrated with 0.0500M NaOH solution. What is the initial pH before adding any titrate?

50.0 mL of 0.185M Sr(OH)2 is reacted with 35.0 mL of a solution containing 0.120g of HCl. Calculate the pOH resulting from the mixture. Then suggest an indicator that will be effective for this incomplete titration and explain your choice.

A cell phone manufacturer predicts pre-orders of their new cell phone using the function: P(d)=-2\sqrt(-d)+20 P=pre-orders(in millions) of the phone d=days before the release date *if you search the graph up on desmos or a graphing site you will see the y...

By what mass (in grams) will a chromium cathode increase when it is coupled to a magnesium half cell in which the magnesium anode loses 1.53 grams? (assuming chromium ions in solution are Cr^3+).

Determine whether the following reaction will occur by determining the voltage produced; Ag(s) + HCl(aq) =

The most common method of producing bromine involves oxidizing bromine ions (Br^-) to bromine liquid (Br2) using chlorine gas (Cl2). What is the E for this reaction?

What reaction (oxidation or reduction) occurs at an anode of... a) an electrochemical cell OR b) an electrolytic cell

An iron bar is to be electroplated with zinc. Draw a diagram to do so and: -Identify what will act as the two electrodes for the cell -identify each electrode as either the anode or cathode -write the half-reactions occurring at each electrode -identify a...

I know how to do the pH afterwards but what's confusing me is that sub into the E line part? Like; 1.00x10^-5 = (H^+) (what goes here though) / (what value goes here?) How can I find the other values for A- and HA to fill in so I can solve for H+?

Apologies I couldn't figure out how to create the square root sign on my pc. Thank you for the understanding of the range.

I would greatly appreciate it if you could show me the long way walkthrough. Thank you!
