Convert the following from mg/L as CaCO3 to mg/L as the ion or compound. of metal is _____. There are other chemicals that are present, depending on the source of mineral. BYJU’S online equivalent weight calculator tool performs the Solution for What is the equivalent weight of an organic acid if 44.00 mL NaOH solution (1.000 mL ≎ 1.100 mL HCl ≎ 0.01001 g CaCO3… A water supply with a hardness of 100 ppm contains the equivalent of 100 g of CaCO3 in 1 million g of water or 0.1 g in 1 L of water (or 1000 g of water since the density of water is about 1 g/mL). View solution C l F 3 ( molecular weight, M 1 ) can oxidize U F 4 ( g ) (molecular weight, M 2 ) … Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis. I was wondering how I'd go around calculating the equivalent weight of CaO. For example, the hardness in water that is caused by calcium, magnesium, and other ions is usually described as calcium carbonate equivalent. Equivalents/L of CaCO3 = conc (g/L)/equivalent weight. =magnesium (mg/L)/equivalent weight of magnesium Example:-A sample of water contains 24 mg/L magnesium. 30. To convert calcium as CaCO3 to the elemental form of just calcium, multiply the Ca hardness value by 0.4. Weight W 1 = 10 N @ 30 degree at a radius of 15 cm and weight W 2 = 15 N @ 270 degree at a radius of 10 cm. The equivalent value is determined using the molecular weight and valence of the chemical species. Here are examples of how to calculate the normality of a solution . Thus the equivalent weight of $\ce{Ca3(PO4)2}$ is 1/2 of its molecular weight. Click to see full answer Hereof, what is the mass of Na2CO3? Since the molecular weight of OH-is 17 g/mol, the conversion is as follows: Hydroxide Alkalinity as OH-(mg/L) = 2 3 Equivalent Weight Calculator is a free online tool that displays the equivalent weight for the given molecular weight and valency value of a chemical reaction. Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate equivalent is one of the key components in agricultural lime. eq wt = $\dfrac{1}{2}\cdot 310.2 = 155.1 $ NOTE Equivalent weight is sort of a peculiar notion and is sometimes not unique. The equivalent weight of CaCO3 = ½ MW CaCO3 = 50 g/equivalent (in a complex-formation reaction, the equiv weight is that weight which reacts with or provides one mole of the reacting cation if it is univalent, or one-half mole if divalent, one-third mole if … One equivalent weight of an element, compound, or ion is the weight in grams of that substance which would react with or replace one gram of hydrogen. Equivalent Weight of H 3 P O 3 = B a s i c i t y M o l e c u l a r w e i g h t o f H 3 P O 3 (M) Since, H 3 P O 3 is a dibasic acid i.e it has two hydrogen ions to donate to a base in acid - base reaction. So (You can imagine that one Na of Na2CO3 has been used by an acid) Therefore equivalent weight is Molecular weight / 1, or molecular weight itself. From my knowledge, the EW of a compound is its (given mass )/(valence factor, n). Normality is the only concentration unit that is reaction dependent. a. In the case of NaHCO3 there is only one Na+ to react with acids. Additionally, what is CaCO3 equivalent hardness? Totally depends on the reaction. Therefore in case of Na2CO3 equivalent weight is Molecular weight / 2. area per unit weight of material than coarser grades. For reduction/oxidation reactions: n-factor is defined as the number of moles of electrons accepted/gained per mole of the substance. Magnesium carbonate is a magnesium salt with formula CMgO3. Calcium carbonate is a chemical compound with the formula CaCO3. Its hydrated forms, particularly the di-, tri-, and tetrahydrates occur as minerals. 2CO2 + 2 electrons → C2O4(-2) Here n-factor is 1. Table 2 shows the rate of change in soil pH over a 3-year period from lime applications of various parti-cle sizes. Equivalent weight of CaCO3 =50 Answerve Hope Helps You sankujitbiswas26 sankujitbiswas26 Answer: Equivalent mass of Ca in CaCO3 = 50g. calcium carbonate (CaCO 3) equivalent An expression of theequivalent E.W= Molecular weight / # of ions = 100.09 (mg/mmol) /2 (meq/mmol) =50.043 mg/meq Generally dolomitic lime contains 25-30% CaCO3. ppm as CaCO3 is expressed as the equivalent weight of the ion mg/l (milligrams per liter) is weight per volume where 1 mg/L numerically = 1 ppm (as the ion weight) at specific gravity =1.
