PROCEDURE for m-ALKALINITY  test ( STEP WISE )
1.1 >> Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
1.2 >> Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .
1.3 >> Add RXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish (salmon) pink  colour develop.
RESULT  : Each DROPS is equivalent to  25 PPM of m- Alkalinity
m-Alkalinity VALUE = 25 X ( Total Number of DROPS of TK9 , during 1.3 step  )
 
C.) PROCEDURE for TOTAL ALKALINITY ( VALUE of A + VALUE of B )
2.1

Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
2.2

Add 1-2 drops of  RXSOL TK7 and mix with the stirring rod , If  sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4.
2.3

Add RXSOL TK9  drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 15 ppm of p-Alkalinity , expressed as CaCO3 
2.4 Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .
2.5

AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish ( salmon ) pink  colour develop.
RESULT Each DROPS is equivalent to 25 PPM of Alkalinity
NOTE

p-Alkalinity ppm CaCO3VALUE   =  25 X ( Total Number of DROPS of TK9 , during 2.3 step  )  = X ( Say )
m-Alkalinity ppm CaCO3VALUE  =  25 X ( Total Number of DROPS of TK9 , during 2.5 step  )  = Y ( Say )
Total Alkalinity ppm CaCO3VALUE  =  X+Y
