Water-soluble salts of water-soluble nitrogenous bases and acid copolymers, said copolymers being insoluble and not swellable in water and having a relative viscosity of at least 1.4 and less than 3.5 measured in solutions of 1 gram of copolymer dissolved in 100 ml. of dimethyl formamide at 25...
NaCl is Sodium Chloride (common salt); CaSO4is Calcium Sulphate. The salt ions normally stay in solution. The salt crystalizes out when the water is removed. Some salts are insoluble. They will precipitate out when the acid and base are added together. Barium Chloride behaves like this: 2HCl...
Insoluble substance which neutralise acids to form a salt and waterProton acceptors What are alkalies Alkalies are bases that are soluable. Strong alkalis produce lots of OH- ions in water and weak alkalis produce few OH- in water What is the pH of alkalis? 8 - 14 Base + Acid Salt + ...

Which of the following salts is insoluble in water? A. Na_2S B. K_3PO_4 C. Pb(NO_3)_2 D. CaCl_2 E. All of these are soluble in water.Which of the following will be more soluble in an acidic solution than in pure water? a. SrSO_...
Bipolar membrane electrodialysis of multivalent metal salts whose corresponding base is insoluble Bipolar membrane electrodialysis methods for salt splitting polyvalent metal salts, where the metal cation can form substantially insoluble precipitates in the presence of hydroxyl ions can now be used in recover...
In this reaction, X has got a nominal charge of + 1 and represents freely dissolved cations that eventually serve as the counterions of the partially insoluble phosphate reaction products. The d-spacings consistent with the reactants and reaction products were found in both carbonate and pho...
Insoluble inorganic titanium salts, such as titanium oxid, are being formed when strong bases such as sodium or potassium alkoxides are being added to a solution of titanium catalysts. Using 1-cyclohexylethyl amine as a salt forming agent rather than using a sodium- or potassium-containing base...
there is a need for providing less expensive amino acids for potential use in this new acid gas scrubbing process. Also, there is a need to find a more suitable alternative to N-cyclohexyl-1,3-propanediamine which performs as well, but does not degrade or form insoluble or undesirable by-...
For example, iron(III) hydroxide (Fe(OH)3) is insoluble in neutral or acidic solutions, but can be dissolved in alkaline solutions, according to the reaction: Fe(OH)3 + OH- → [Fe(OH)4]- The alkalinity of the solution causes the hydroxide ions (OH-) to react with the iron(III) ...
