Gather the necessary measurements. You'll need your water's pH, calcium hardness, total alkalinity, and water temperature. Go to our Langelier Saturation Index Calculator page. Enter the required measurements into the appropriate fields. Click "Calculate" to get your water's LSI. ...
Therefore, the total dissolved solids test provides a qualitative measure of the amount of dissolved ions but does not tell us the nature or ion relationships. In addition, the test does not provide us insight into the specific water quality issues such as hardness, salty taste, staining, ...
determine the number of covalent bonds that are possible for atoms of the following elements: germanium, phosphorus, selenium, and chlorine. 2.24 On the basis of the hydrogen bond, explain the anomalous behavior of water when it freezes. That is, why is there volume expansion upon solidification...
Determine the total water hardness in a 25.00 mL sample of water that required 12.45 mL of 0.01111 M EDTA for titration. A titration is performed with 50 mL of 0.1 M Ca2+ and 0.1 M EDTA at pH 10. Calculate pCa after addition of 30mL of the ...
