what are total ionic equation?
436483
The complete ionic equation is used to describe the chemical reaction while also clearly indicating which of the reactants and/or products exist primarily as ions in aqueous solution. To write the complete ionic equation: Start with a balanced molecular equation.

Total Dissolved Solids. Total dissolved solids is a measurement of everything that has ever dissolved in your swimming pool water. This includes minerals that separate from your pool chemicals, such as calcium and sodium, and every bit of dissolved dust, pollen, swimmer waste, algae remains – everything!

The autoionization of liquid water produces OH− and H3O+ ions. The equilibrium constant for this reaction is called the ion-product constant of liquid water (Kw) and is defined as Kw=[H3O+][OH−]. At 25 °C, Kw is 1.01×10−14; hence pH+pOH=pKw=14.00.

Determining Empirical Formulas. An empirical formula is one that shows the lowest whole-number ratio of the elements in a compound. Because the structure of ionic compounds is an extended three-dimensional network of positive and negative ions, all formulas of ionic compounds are empirical.

All ionic compounds are soluble in water to some extent, but the degree of solubility varies. While some compounds dissolve almost completely, others dissolve to such a small extent that they are simply called insoluble compounds. Such compounds include calcium sulfate, silver chloride, and lead hydroxide.

Ionic half equations. A half-equation shows you what happens at one of the electrodes during electrolysis . Electrons are shown as e -. A half-equation is balanced by adding, or taking away, a number of electrons equal to the total number of charges on the ions in the equation.

The equation is: charge (coulomb, C) = current (ampere, A) × time (second, s). For example, if a a current of 20 A flows for 40 s, the calculation is 20 × 40.

Both ionic product and solubility product represent the product of the concentrations of the ions in the solution. ... On the other hand, the term solubility product is applied only to a saturated solution in which there exists a dynamic equilibrium between the undissolved salt and the ions present in solution.

What is the molecular formula of zinc phosphate? The ionic state of Zinc is Zn+2 and the ionic state of phosphate is (PO4)-3. Phosphate molecules need three other atoms or molecular groups to balance and zinc needs two other atoms or molecular groups to balance.

In general, the solubility product constant (Ksp), is the equilibrium constant for the solubility equilibrium of a slightly soluble ionic compound. Like all equilibrium constants, the Ksp is temperature dependent, but at a given temperature it remains relatively constant.

Electrolytes are substances which, when dissolved in water, break up into cations (plus-charged ions) and anions (minus-charged ions). We say they ionize. Strong electrolytes ionize completely (100%), while weak electrolytes ionize only partially (usually on the order of 1–10%).
