What ions separate from acids in solution?
When acids are dissolved in water, they donate hydrogen ions (H+). The specific ions that separate from acids in solution depend on the type of acid. For example, hydrochloric acid (HCl) separates into hydrogen ions (H+) and chloride ions (Cl-), while sulfuric acid (H2SO4) separates into hydrogen ions (H+) and sulfate ions (SO4^2-).
What is valency oxalic acid?
Oxalic acid has a valency of 2, as it can donate two hydrogen ions in a chemical reaction. This makes it a dicarboxylic acid.
Gram equivalent weight of EDTA?
The gram equivalent weight of EDTA (Ethylenediaminetetraacetic acid) is calculated by dividing its molar mass by the number of acidic hydrogen ions it can donate. Since EDTA can donate 4 acidic hydrogen ions, its gram equivalent weight is typically 372 g/mol divided by 4, which equals 93 g/equivalent.
What is equivalent mass of sulfuric acid?
The equivalent mass of sulfuric acid (H2SO4) is calculated as its molar mass divided by the number of replaceable hydrogen ions it can donate. Since sulfuric acid can donate 2 hydrogen ions (H+), the equivalent mass is half of the molar mass. Therefore, the equivalent mass of sulfuric acid is approximately 49 g/mol.
What elements make up calcium hydrogen carbonate?
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
How can calculate equivalent weight of calcium carbonate?
The equivalent weight of calcium carbonate can be calculated by dividing its molecular weight by the number of acidic hydrogen ions that it can donate in a reaction. In the case of calcium carbonate, it can donate two moles of hydrogen ions, so the equivalent weight would be its molecular weight divided by 2.
An arrhenius acid has 1.only hydroxide ions in solution. 2.only hydrogen ions in solution. 3.hydrogen ions as the only positive ions in solution. 4.hydrogen ions as the only negative ions in solut?
An Arrhenius acid has only hydrogen ions in solution.
Give an example of an diprotic acid?
The most common diprotic acid is sulphuric acid; H2SO4(aq) as this has 2 H+ to donate.
What iaons are present when HClO4 is dissolved in water?
H+ (hydrogen ions) and ClO4- (perchlorate) ions are produced (along with the H+ and OH- from water itself).
How many h ions can the acid H2SO4 donate per molecule?
it can donate a maximum of 2, but may only donate 1 due to the amount of dissociation that occurs. if the acid is added to water, the first hydrogen will be lost in the reaction: H2PO4 <===> HPO4- + H+ The next reaction may or may not occur due to the dissociation of the first H+. if the first hydrogen has remained, then the second will not dissociate as the concentration of hydrogens is too high, and the backwards reaction may take place, where the negative, single hydrogen ion will accept the hydrogen as it is a conjugate base, creates the original reactant.
What have the smallest number hydrogen ions pH 2 or pH 6?
A pH of 2 has a higher concentration of hydrogen ions than a pH of 6. This is because pH is a measure of the concentration of hydrogen ions in a solution, and the lower the pH value, the higher the hydrogen ion concentration.
What are 2 ions that are the products of dissociation of water?
hydrogen and water
