sir i’ve gone via yours wall wash blog and the above blog.
Within the above KMnO4 PTT test, If the zero.02% KMnO4 just isn’t accessible onboard, we can make it onboard by putting 0.1gram in 500cc DI water. Do we have to anticipate 1.5hrs to dissolve the solids in DI water before we use is as 0.02%KMnO4.?
It’s understood that PTT test is consequence change in color from purple pink to straw yellow in a certain time/temp. But how we will come to know weather our PTT check is pass or fail. ? Such as you talked about, 50 mins at 15c, 30 mins at 20c. means will the coloration change in 50mins at 15c?
And the statement, Underneath purest condition KMnO4 check will run for a hundred and twenty mins.?
Also sir, In your wall wash blog below the CL test, you talked about use UNFILTERED wash for testing.
under HC take a look at, You simply mentioned WASH for testing and in above case FILTERED wash..
Do we want to use whatman fifty two filter paper to filter the test methanol prior utilizing for PTT take a look at.?
And sir if you happen to please explain the tank high testing process briefly. I’ve read in wall wash weblog which says that use filter paper to absorb the methanol from the ground and put the paper in sample bottle and add 50cc check methanol for each filter paper.
