Which base is a weak electrolyte A. sodium hydroxide B. potassium hydroxide C. calcium hydroxide D. ammonia?
D. Ammonia is a weak electrolyte because it only partially ionizes in water to form ammonium ions and hydroxide ions, resulting in a low concentration of ions in solution compared to strong electrolytes like sodium hydroxide, potassium hydroxide, and calcium hydroxide.
What are the elements of magnesium hydroxide?
Magnesium hydroxide consists of magnesium cations (Mg2+) and hydroxide anions (OH-). These combine in a 1:2 ratio to form the compound, with each magnesium ion attracting two hydroxide ions through ionic bonding.
What salt would form from a reaction between hydrochloric acid hci and calcium hydroxide ca oh2?
Calcium chloride would be formed from the reaction between hydrochloric acid (HCl) and calcium hydroxide (Ca(OH)2), as hydrogen from the acid combines with the hydroxide from the base to form water, leaving behind calcium and chloride ions that combine to form calcium chloride (CaCl2).
What would the formula be if calcium and hydroxide became a compound?
As calcium forms the 2+ ion, and hydroxide has a negative charge, the formula would be Ca(OH)2
What type of reaction is sodium bromide mixed with calcium hydroxide?
The reaction between sodium bromide and calcium hydroxide is a double displacement or metathesis reaction. In this reaction, the sodium and calcium ions switch partners to form sodium hydroxide and calcium bromide.
Do the ions combine in a 11 ratio?
No, ions combine in whole number ratios to form neutral compounds based on their charges. For example, in calcium chloride (CaCl2), calcium ions with a 2+ charge combine with chloride ions with a 1- charge in a 1:2 ratio to form a neutral compound.
What does calcium phosphate combine with?
Calcium phosphate can combine with various ions such as hydroxide, carbonate, and fluoride to form different compounds like hydroxyapatite, calcium carbonate, and calcium fluoride.
Which reactants form the salt CaSO4(s) in a neutralization reaction?
Calcium sulfate (CaSO4) is formed when calcium hydroxide (Ca(OH)2) and sulfuric acid (H2SO4) react in a neutralization reaction. The hydroxide ions from the calcium hydroxide combine with the hydrogen ions from the sulfuric acid to form water, while the calcium ions and sulfate ions combine to form calcium sulfate.
What is the chemical formula of calcium and hydroxide?
Calcium Hydroxide has a molecular formula of Ca(OH)2. The structural formula is H-O-Ca-O-H.
What chemical reaction happens when lime and acid is combined?
When lime (calcium hydroxide) is combined with an acid, a neutralization reaction occurs resulting in the formation of water and a salt. The calcium in lime reacts with the acid to form calcium ions, while the hydrogen ions in the acid combine with the hydroxide ions in the lime to form water.
What happens to the sodium and hydroxide ions after electrolysis?
The sodium ions combine with water molecules to form sodium hydroxide, while the hydroxide ions combine with hydrogen ions to form water. This process results in the production of sodium hydroxide and hydrogen gas.
Is calcium hydroxide a weak electrolyte?
No, calcium hydroxide is a strong electrolyte. When dissolved in water, it completely dissociates into calcium ions (Ca2+) and hydroxide ions (OH-), resulting in a high degree of conductivity.
What is the ksp expression for calcium hydroxide?
The Ksp expression for calcium hydroxide is Ksp = [Ca2+][OH-]^2, where [Ca2+] is the concentration of calcium ions and [OH-] is the concentration of hydroxide ions in the saturated solution of calcium hydroxide.
What is the solubility product of calcium hydroxide?
The solubility product (Ksp) of calcium hydroxide is approximately 5.5 x 10^(-6) at 25°C. This value represents the equilibrium constant for the dissociation of calcium hydroxide into calcium ions and hydroxide ions in a saturated solution.
What happen when we put water into lime water?
When water is added to lime water (which is a saturated solution of calcium hydroxide), the calcium hydroxide dissociates into calcium ions and hydroxide ions. This results in the formation of a milky white precipitate of calcium carbonate due to a chemical reaction between the calcium ions and carbon dioxide in the air.
Which base is a weak electrolyte A. sodium hydroxide B. potassium hydroxide C. calcium hydroxide D. ammonia?
D. Ammonia is a weak electrolyte because it only partially ionizes in water to form ammonium ions and hydroxide ions, resulting in a low concentration of ions in solution compared to strong electrolytes like sodium hydroxide, potassium hydroxide, and calcium hydroxide.
Is calcium sulfate a salt base or acid?
Calcium sulfate is a salt because it is formed from the reaction between a base (calcium hydroxide) and an acid (sulfuric acid). It is a neutral compound with a 1:1 ratio of calcium ions (from the base) to sulfate ions (from the acid).
