Formation of tricalcium phosphate
To calculate theoretically the pH of
Saturation of trlcaldum Phosphate of a known water quality:
|
Step 1
-
Obtain Calcium Factor from Table 1.
|
TABLE 1.
Calcium Factor for Calculation of pHS of
tricalcium Phosphate
|
Step 2 -
Obtain Phosphate Factor from Table 2.
|
TABLE 2
Phosphate Factor for Calculation of pHs of Tricalcium
Phosphate
|
| Step 3 -
Total factors from steps 1 and 2 : Enter table 3 at correct
temperature range
— Read pHs
from left column.
|
TABLE 3
pH Temp. Factor for Calculation, of Trlcalcium
Phosphate DH-Temperature formation
|
Analysis:
 | If the actual pH is less than pHs,
Ca3(PO4)2 will tend to go Into
solution. |
| If the actual pH equals pHs,
water is balanced. |
| If the actual pH exceeds the pHs,
Ca3(PO4)2 will tend to
precipitate. |
