Hydroxide

basic compound donates a hydroxide anion which collectively form a product containing salt and water. The dissociation of the acid and base allows for the formation of the salt and water. Similarly, antacids are formulated to neutralize the hydrochloric acid present in the human…

QUESTION Explain the significance and optimum value of the following parameter i. pH ii. DO iii. TDS iv. COD v. BOD ANSWER pH ph is the concentration of hydronium ion. It represents the ratio of hydronium ions (H3O + ) to Hydroxide ion (OH- ). It is numeric scale which decides the basic and alkalinity of water. If the ph of the solution is less than 7 than then the solution is said to alkaline and if the ph is greater then 7 then the solution is said to be basic. The ph of pure water at 25o C is…

the chlorination of milk of lime. It is produced by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite, which disproportionates when heated with excess chlorine to give calcium chlorate and calcium chloride: 6Ca (OH)2 + 6 Cl2 → Ca(ClO3)2 + 5 CaCl2 + 6H2O. “The big problem with making calcium chlorate is the buildup of calcium hydroxide on the cathode which prevents current from flowing through the cell soon after the cell is started. The…

following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver nitrate (AgNO3), Lead (II) nitrate (Pb(NO3)2), Hydrochloric acid (HCl), Ammonia (NH3), Water (H2O). From the substances above Hydrochloric acid (HCl) is…

oxides is then heated with the ferrosilicon which forms calcium silicate and magnesium [7] The extraction of magnesium from seawater is a completely different operation which relies on the fact that magnesium hydroxide is less soluble than calcium hydroxide. So to extract the magnesium hydroxide they add CaO to seawater and because its more soluble it displaces the Mg(OH)2 forming a precipitate [6]. The precipitate is then treated with hydrochloric acid. As an equation it would look like this:…

(Adams 297) Why these processes occurred in the body of a young guy? Because of the ingredients and methods of producing the fast-food. During a lawsuit Oliver v. “McDonald’s”, the plaintiff James Oliver has proved, that the defendant used ammonium hydroxide (food additive E-527) for the meat as a regulator of acidity. For oral use, it is considered dangerous, causes indigestion and adversely affects the liver. In fact, all these delicious cutlets in hamburgers are made from pennies of…

funnel. In conclusion, the margin of error from the percent recovery and the success of the TLC plates makes this experiment partially successful. The second experiment’s goal was to synthesize 9-fluorenone using hydroxylamine hydrochloride, sodium hydroxide, and ethanol.4,7 The synthesis starts with an acid-base reaction with sodium hydrochloride and hydroxylamine hydrochloride salt.7 This results in the nitrogen of the hydroxyl amine becoming a nucleophile and attacking the carbonyl (the…

flask were stirred for a period of 15 min, and then the solution was heated to 40 , 0.5 mol p-methylcyclohexanone was introduced drop wise to the solution for about 3 h. Then the mixture was poured into 60 mL boiling water containing 2N potassium hydroxide. The solid product was separated and acidified with dilute sulphuric acid, then washed with distilled water and dried at 45 for 12 h. Recrystallization from benzene and the methanol – water system gave light yellow crystals. The synthesis of…

The kinetics of the reaction between peroxomonosulphate with Lactic acid was studied in the presence of Mn(II) at alkaline pH. The reaction followed first order with respect to peroxomonosulphate. The rate of the reaction was studied under pseudo first order condition and found to increases with the [Mn(II)] and lactic acid. Thermodynamic parameters were calculated and reported. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted. Keywords: Alpha…

precipitate, indicating sulfate ions' presence; see Table 2 of week 1 for results. Then we moved on to our cation test; this test involved a pH test, flame test, and more reaction tests. In one of our tests, we reacted ammonium nitrate with sodium hydroxide to create a solution; then, we tested the solution with pH and turmeric powder, which…
