						PROCEDURE for m-ALKALINITY  test ( STEP WISE )  | 
			|
| 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 )  |
