K₃PO₄ → 3K⁺ + PO₄³⁻
PO₄³⁻ + H₂O ⇄ HPO₄²⁻ + OH⁻
HPO₄²⁻ + H₂O ⇄ H₂PO₄⁻ + OH⁻
H₂PO₄⁻ + H₂O ⇄ H₃PO₄ + OH⁻
K⁺, PO₄³⁻, HPO₄²⁻, H₂PO₄⁻, OH⁻
Answer:
False
Explanation:
The displacement method is not used to find the volume of irregularly shaped objects. Rather the opposite.
Answer:
Explanation:
If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited. They are then called degenerate energy levels.
Yes, It is important to know the volume of Unknown acid or base to be titrated.
Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.
M₁V₁/n₁ = M₂V₂/n₂
Answer:anions with least precipitates are anions of salt produce by a strong acid and strong base e.g KCL,Na2SO4,
Explanation: salts produce from strong acid such as HCL and a strong base such as KOH are extremely soluble and hence produce little or no precipitate when dissolved in water .meaning the salt are highly soluble , most group1 elements form salts that are highly soluble and hardly precipitates e.g Na(sodium) pottasium(K) ,lithium(Li)salts.they are called alkaline metals.
B) exception to the rules are hydrogen and Rubidium.hydrogen because it occurs basically as a gas and forms H^+ which tend to form a hydrogen bond while rubidium is a heavy metal forming insoluble salt
