Aluminum chloride (AlCl3) is a Lewis acidbecause the aluminum atom has an open valence shell. ... According to Lewis, a species is an acid if it is electron deficient and accept lone pair of elections. So AlCl3 is a Lewis acid. Is na2co3 an acid or base? Na2CO3isa basic saltformed f...
0.050 mol/L Na_2CO_3(aq) List the four given bases from the strongest base to the weakest base.List the bases from strongest base to weakest base. a. 0.10 mol/L Na2CO3(aq) b. 1.0 mol/L Li2OOCCOO(aq) c. 2.0 x 10-2 mol/L NaOH(aq) d. 0.50 mol/L K2SO4(aq)List the follow...
Sodium carbonate is a basic salt because it is a salt of A strong acid and strong base B weak acid and weak base C strong acid and weak base D weak acid and strong base Video SolutionText SolutionGenerated By DoubtnutGPT The correct Answer is:DTo determine why sodium carbonate (Na2CO3)...
Write the equation for the dissociation of the weak base CO3. Complete the reaction then give the expression for the Ka for H2S in water. H_2S + H_2O Leftrightarrow Blank + H_3O^{+1} Which base would be best to deprotonate cyanophenol in an...
A buffer is a solution that consists of a mixture of a weak acid and its conjugate base. True False Buffers can resist pH change by providing a weak base to neutralize added acid. Is the statement true or false? True or false? A 0.05 M solution of an acid...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Winter wheat cultivars are also classified into three types according to the quantitative variation in the duration of low temperature required to reach a vernalization saturation point: weak winter types, semi-winter types, and strong winter types12. The positional cloning of a major quantitative ...
It also showed weak activity toward PNP-α-Galp and 1.5% activity toward PNP-β-l-Arap but did not hydrolyze any other PNP glycosides, including PNP-α-N-acetylgalactosaminide. Because the structure of β-l-arabinose and α-galactose are similar, kinetic study was performed using PNP-β-l...
Buffers A buffer is a solution that resists changes in pH. The pH of a buffer changes very little when small amounts of a strong acid or strong base are added to the buffer. A buffer consists of approximately equal amounts of a conjugate weak acid/weak base pair in equilibrium with each...
In this calculation it is assumed that there is no weak conjugate base present initially and the equilibrium molarity of this weak base species is very small, relative to the starting weak acid molarity. The situation is different in a buffer solution be...
