Solved examples on Chlorate Formulas:
Example 1: What is the formula for a compound formed when barium reacts with chlorate?
Answer: The barium cation has a charge of +2, while the chlorate anion has a charge of -1.
To balance the charges, we need two chlorate ions for every barium ion.
Therefore, the formula for the compound formed is Ba(ClO3)2.
Example 2: How many oxygen atoms are present in one molecule of calcium chlorate?
Solution: The formula for calcium chlorate is Ca(ClO3)2.
In one chlorate ion (ClO3-), there are three oxygen atoms.
Since there are two chlorate ions in the formula, we multiply the number of oxygen atoms by 2.
Therefore, there are a total of 6 oxygen atoms in one molecule of calcium chlorate.
Frequently asked questions on Chlorate
1: What are the common uses of chlorate?
Answer: The common uses of chlorates:
– Source of Oxygen: Chlorates have been used as a source of oxygen in explosives, matches, and fireworks.
– Bleaching Agent and Disinfectant: Chlorates are employed in the production of chlorine dioxide (ClO2), which is a powerful bleaching agent and disinfectant.
– Herbicides and Defoliants: Chlorates have historically been used as herbicides and defoliants in agriculture to control weeds and promote plant growth. However, their use in this context has been restricted or banned in some countries due to safety concerns.
– Chemical Manufacturing: Chlorates find applications in the manufacture of certain chemicals, such as dyes, herbicides, and insecticides.
2: What is another name for chlorate?
Answer: The another name for chlorate is Hypochlorite.
3: What is the source of chlorate?
Answer: Chlorates can be synthesized through various chemical processes rather than being sourced directly from natural materials. They are typically produced by the electrolysis of a chloride salt solution, such as sodium chloride (NaCl), in the presence of an oxidizing agent. This process involves passing an electric current through the solution, resulting in the formation of chlorate ions (ClO3-) at the anode. The chlorate ions can then be isolated and further processed to obtain chlorate compounds or used directly in specific applications. It’s important to note that the production of chlorates requires careful handling and control due to their oxidizing properties and potential hazards.
4: What removes chlorate from water?
Answer: There are several methods that can be used to remove chlorate from water:
– Activated Carbon Filtration: Activated carbon filters can effectively remove chlorate from water through adsorption. The activated carbon has a high surface area that can trap and retain chlorate molecules as water passes through the filter.
– Reverse Osmosis: Reverse osmosis (RO) is a water purification process that uses a semipermeable membrane to remove impurities, including chlorate. The membrane allows water molecules to pass through while blocking larger molecules, such as chlorate ions.
– Ion Exchange: Ion exchange resins can be used to remove chlorate from water. These resins have an affinity for chlorate ions and can exchange them with other ions, effectively reducing the chlorate concentration in the water.
– Chemical Reduction: Chlorate can be chemically reduced to chloride using reducing agents, such as sulfur dioxide (SO2) or hydrogen peroxide (H2O2). These agents react with chlorate ions, converting them into chloride ions, which are less harmful.
– Electrochemical Methods: Electrochemical processes, such as electrolysis, can be employed to remove chlorate from water. By applying an electric current, the chlorate ions can be converted into other compounds or deposited onto an electrode, effectively reducing their concentration in the water.
5: Is chlorate harmful or dangerous?
Answer: Chlorate can be hazardous and potentially dangerous due to its strong oxidizing properties. It can react violently with combustible materials and can pose fire and explosion risks if mishandled. Ingesting or inhaling chlorate compounds can also be harmful to human health. Therefore, it is important to handle chlorates with proper precautions and follow safety guidelines when working with or around these substances.
6: Can chlorate be used as a weedkiller?
Answer: Chlorates were historically used as weedkillers due to their ability to inhibit plant growth. However, their use as herbicides has been restricted or banned in many countries due to safety concerns. Chlorates have been found to contaminate soil and water, posing risks to the environment and human health. Safer and more environmentally friendly alternatives have been developed for weed control purposes. It is important to check and comply with local regulations regarding the use of herbicides and follow recommended practices for sustainable and responsible weed management.
7: Is ClO4 a chlorate?
Answer: No, ClO4 is not a chlorate. The correct formula for the chlorate ion is ClO3-.
8: What shape is ClO3?
Answer: The chlorate ion (ClO3-) does not have a specific shape as it is an ion composed of three atoms: one chlorine atom (Cl) and three oxygen atoms (O). However, it can be described as having a trigonal planar arrangement, with the chlorine atom at the center and the three oxygen atoms surrounding it.
9: Is ClO3 an acid?
Answer: The chlorate ion (ClO3-) is not an acid. It is the conjugate base of chloric acid (HClO3), which is an acid. When chloric acid loses a hydrogen ion, it forms the chlorate ion, ClO3-. The chlorate ion is a negatively charged species and does not act as an acid itself.
