## What is the chemical equation for KHP and NaOH?

We have a balanced chemical equation in which we now know the exact quantity of one of the reagents (KHP) – NaOH(aq) + KHC8H4O4(aq) = KNaC8H4O4(aq) + H2O(l) – thus we can determine the number of moles of NaOH that reacted with the KHP. These are two terms that often lead to some confusion.

## What is the reaction between KHP and NaOH?

reaction is called a neutralization reaction because two caustic compounds, KHP, a mild acid, and NaOH, a strong base, are replaced by water and a weaker base.

## What is the net ionic equation for the reaction between HClO and NaOH?

HClO4 + NaOH = NaClO4 + H2O is a neutralization reaction (also a double displacement reaction). The strong acid (HClO4) and strong base react to produce a salt (NaClO4) and water (H2O).

C8H5KO4

## Why do we use NaOH in titration?

During the course of the titration, the titrant (NaOH) is added slowly to the unknown solution. After the equivalence point, there will be an excess of NaOH and the solution will be basic. An acid-base indicator can be used to help identify when the change from acidic to basic occurs.

## What’s the molarity of NaOH?

The molarity of a sodium hydroxide solution can be determined by dividing the amount of sodium hydroxide (in moles) present by the number of liters of the overall solution. >> For example, if there are 50 moles of NaOH in 500 liters of solution, it is a 0.1 molar NaOH solution.

## How do you standardize NaOH?

To standardize NaOH, start by pipetting 10.0 ml of 0.1 N hydrochloric acid (HC1) into a flask. Add approximately 50 ml of water (remember, not tap water) and three drops of methyl red indicator. Fill a 25 ml buret with the 0.1 N sodium hydroxide solution and record the initial volume.

## Why do we need to standardize NaOH?

Solid NaOH is highly hygroscopic (it absorbs water from the air) and thus it cannot be accurately weighed. A KHP sample of known mass (and, therefore, known moles) can be titrated with the NaOH solution to determine very precisely the concentration of the NaOH. Originally Answered: Why do we standardize NAOH?

## What happens when NaOH reacts with ch3cooh?

The reaction of Sodium hydroxide and Acetic acid (also called Ethanoic acid) represents a net ionic equation involving a strong base and a weak acid. The base (NaOH) and weak acid (CH3COOH) react to produce a salt (NaNO3 and water (H2O).

## What is a full ionic equation?

A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions. Identify and cancel out the spectator ions (the ions that appear on both sides of the equation).

## Which is a net ionic equation for the neutralization?

An Arrhenius acid increases the amount of H + ions in an aqueous solution. Because the salts are soluble in both cases, the net ionic reaction is just H +(aq) + OH (aq) → H 2O(ℓ). The difference is simply the presence of an extra water molecule as a product.

## What is the net ionic equation for the reaction between a strong acid and a strong base?

So with a strong acid and strong base, the net ion equation is always H+ plus OH- yields H2O.

## Why do we standardize NaOH with KHP?

Solid NaOH is highly hygroscopic (it absorbs water from the air) and thus it cannot be accurately weighed. A KHP sample of known mass (and, therefore, known moles) can be titrated with the NaOH solution to determine very precisely the concentration of the NaOH. This procedure is called standardizing the NaOH solution.

## How do I calculate molar concentration?

Concentration formula: To find the molar concentration of a solution, simply divide the total moles of solute by the total volume of the solution in liters.

#### H2o2 decomposition equation

What does h2o2 decompose into? Hydrogen peroxide can easily break down, or decompose, into water and oxygen by breaking up into two very reactive parts – either 2OHs or an H and HO2: If there are no other molecules to react with, the parts will form water and oxygen gas as these are more stable […]
