a student spills a small amount of HCl into an aquarium containing 150 l of water reducing the ph from 7.35 to 3.60 what mass of Ca(OH)2 would have to be added to return the ph to its original value

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

Can someone me with 6 to 10 plz this is for masteries test.
