Complete the fow chart wth the steps necessary for diluting a prepared buffer solution. ma make 30 ml of the assigned 1: 1 buffer solution in a clean, labeled 100 ml beakerobtain 30 ml of the strong acidnd trong basestock solutions. measure the phof these solutions. by a factor of 5 by adding a little dl water dilute the buffer solution in a 50.0 ml followed by 5 m of the buffer solution. carefully fill to the line with cogte base and invert 10 times to mix the solution. pour the resulting solution into aclean beaker and record the ph. repeat for the other two . making sure to clean and rinse all glassware between uses. in your pre-lab, prepare a similar procedure for making the 10-fold dilution. 5 ml conjugate base ph 30 ml 50 ml 100 ml 10 10 ml beaker di water strong acid strong base weak acid 5

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
