45 three samples of the same solution are tested, each with a different indicator. all three indicators, bromthymol blue, bromcresol green, and thymol blue, appear blue if the ph of the solution is
(1) 4.7 (2) 6.0 (3) 7.8 (4) 9.9

(4) 9.9 is the most sensible answer.

When an indicator appears blue, that means the solution is basic and the pH of the solution should be within the range of 8 and 14.

Hope this helps~

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
