Total dissolved solids

hydroxide and carbonic acid, and the combined mass of the sodium carbonate and water will be equal. This is because of the Law of Conservation of Mass. The Law of Conservation of Mass states that in any given chemical equation, the total mass of the reactants equals the total mass of the products. During a chemical reaction, the atoms/ions of the reactants are rearranged to form new products. Thus, chemical equations must always be balanced, with the same kinds and numbers of atoms/ions and mass…

Environmental parameters Vs Plankton Incidents: The graphs presented in figureX to figureX, environmental parameters observed at different sites in each area are presented area wise along with the harmful plankton incidents observed. Average temperature, dissolved oxygen and salinity observed each day at each farm site is used to plot these graphs. There has been a notion that with drop in salinity, which means freshwater run off, there would be increase in nutrients and supporting higher…

opposite sides of iron. The “η5” hapticity indicates that five atoms from the Cp ligand are coordinating to the iron ion. The iron contributes six electrons with it’s oxidation state of 2+, and the Cp rings each contribute six electrons. Thus, the total electron count of…

dissolve them if they are already formed. It would be easier to take, or drink, the lemon juice instead of the home remedy mix, since that one would be kind of difficult to drink. Both did dissolve the kidney stones, it’s just that one might have dissolved it with less amount than the…

form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant.” (University Of Wisconsin) The data the was found from our lab shows that the data is not consistent to the Law of Conservation of Mass because our results showed an increase in mass. To start the lab, .7 grams of copper was measured out and at the end, the total amount of copper was .73 grams. Throughout the five reactions, the theoretical yield was…

ABSTRACT Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous system.Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Poor watersolubledrugs often require high doses in order to reach therapeutic plasma concentrations after oral administration. Low aqueoussolubility is the major problem encountered with formulation development of new chemical entities. Any…

precipitation is done using TFA ot TCA upto 10%, followed by evaporation or solid phase extraction to remove the acid. PEGylated proteins of larger sizes, with molecular weight of 40-50 kDa, possess a unique hydrophobicity which allows their precipitation. The PPT step denatures the proteins and removes matrix effect causing componenets. The precipitated proteins are then digested using trypsin and the analysed using LC-MS. • Solid phase extraction (SPE) : This method is used for extraction of…

Nephrotoxicity is associate adverse effect of the anticancer drugs for solid and hematologic malignancies (Kintzel, 2001). Cisplatin, cisplatinum or cis-diamminedichloroplatinum (II) , a platinum-based drug, is one of the most frequently used anti-neoplastic agents. It has a potent anti-tumor action against wide range of malignancies, including testicular, ovarian, cervical, bladder and lung cancers as well as solid tumors resistant to other treatment regimens (Hanigan and Devarajan, 2003).…

AG, Flawil, Switzerland) with a high performance cyclone in a closed-mode. Feed solutions of kanamycin (as sulphate) or/and rifampicin were prepared in a co-solvent system of ethanol and water (70:30, v/v). Rifampicin was first dissolved in ethanol; kanamycin was dissolved in water. The two solutions were then mixed (at rifampicin and kanamycin ratio of 40 and 60% w/w) and sonicated for 5…

titration since calcium carbonate is an insoluble salt and does not dissolve in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed at the end point. This experiment is a success as two results obtained from the experiment were relatively close…
