What is the concentration of each ion in pure water? What is the concentration of lead ions in one liter of saturated {\rm{PbCr\rm{O_4} solution? What is the solubility of silver chromate in parts per million? The amount of CaCO_3 is equivale...
Alkalinity is expressed as ppm calcium carbonate equivalent. The higher the number, meaning the more of these components are found in the water. High alkalinity water may lead to a gradual increase in the growing media pH. Whenever the pH level climbs, the availability of various plant ...
What mass of calcium phosphate forms by the reaction of 50 mL of 0.2 M H3PO4 with 80 mL of 0.1 M Ca(OH)2? 2H2PO4 + 3Ca(OH)2 arrow Ca3(PO4)2 + 6H2O What is the equivalent weight of H_3PO_4 for the given reaction, H_3PO_4 + Ca(OH)_2 to CaHPO_4...
I just want to confirm the correct weight of Epsom Salts needed for the 1l concentrate. In the Example above the calculations comes to 0.246g to get 100ppm. However, in the post before this it states that 2.45g is needed to obtain 1000ppm. Is the 2.45g right or should it be 2.46g?
Are the maths for how much baking soda to add to 1L to get 100ppm exact? Cause I actually add 0,84gr to 1L to get 1000ppm Also how can I find the CaCO3 equivalent for Calcium dihydrate? So I can apply the same maths. Log in to Reply...
