Unlocking the Potential of AgOH: From Synthesizing Silver Nanoparticles to Biomedicine

Properties of Nitric Acid and AgOH

Nitric acid is a colorless liquid that is highly corrosive and a powerful oxidizing agent. It is commonly used in the production of fertilizers, explosives, and dyes.

On the other hand, AgOH or silver hydroxide is a white precipitate that is highly soluble in water and is formed by the reaction between silver nitrate and sodium hydroxide.

Reaction between HNO3 and AgOH

The reaction between nitric acid and silver hydroxide results in the formation of silver nitrate and water. The reaction is represented by the chemical equation:

HNO3 + AgOH AgNO3 + H2O

This is a neutralization reaction between an acid and a base that results in the formation of a salt and water.

In this reaction, HNO3 acts as the acid and AgOH acts as the base. Product, Type, and Balancing of Reaction

The product of the reaction between HNO3 and AgOH is AgNO3 (silver nitrate) and H2O (water).

This is a type of neutralization reaction or acid-base reaction in which an acid and a base react to form a salt and water.

The reaction is already balanced, but it can be represented in a net ionic equation as shown below:

AgOH is an important intermediate in the production of silver nanoparticles, which have numerous applications in electronics, biomedical engineering, and catalysis. The synthesis and functionalization of silver nanoparticles rely heavily on the properties and reactivity of silver hydroxide as a precursor.

Balancing of HNO3 + Al(OH)3

Setting up the equation and using labeled coefficients

To balance the equation of HNO3 + Al(OH)3, we need to ensure that the number of atoms on both sides of the equation is equal. To do this, we must write the chemical equation and use labeled coefficients to balance it.

The unbalanced equation of HNO3 + Al(OH)3 can be written as:

HNO3 + Al(OH)3 Al(NO3)3 + H2O

To balance the equation, we first need to count the number of atoms of each element on both sides of the equation. On the left side, we have one nitrogen atom, three oxygen atoms, three hydrogen atoms, one aluminum atom, and three hydroxide ions.

On the right side, we have one nitrogen atom, three oxygen atoms, four hydrogen atoms, one aluminum atom, and three nitrate ions. To balance the equation, we need to add coefficients to each compound so that the number of atoms is equal on both sides.

We can start by adding a coefficient of three in front of HNO3 and a coefficient of one in front of Al(OH)3 to balance out the aluminum and nitrogen atoms.

3HNO3 + Al(OH)3 Al(NO3)3 + H2O

Now we have three nitrogen atoms, nine oxygen atoms, nine hydrogen atoms, three aluminum atoms, and nine hydroxide ions on the left side.

On the right side, we have three nitrogen atoms, nine oxygen atoms, nine hydrogen atoms, three aluminum atoms, and three nitrate ions. To balance out the hydroxide ions, we can add the coefficient of three in front of the product, nitric acid.

Therefore, the balanced equation of HNO3 + Al(OH)3 is:

3HNO3 + Al(OH)3 Al(NO3)3 + 3H2O

Calculating parameter values using Gaussian elimination method

The Gaussian elimination method is a mathematical technique used to solve a system of linear equations. In the case of balancing chemical equations, we can use this method to calculate the coefficients of each compound in the equation.

To use the Gaussian elimination method, we can start by writing the coefficients of each compound in a matrix form. We then reduce the matrix to its row echelon form and solve for the coefficients.

For the equation of HNO3 + Al(OH)3:

H: 1 0 3 0 H: 1 0 3 0

N: 1 0 0 3 N: 1 0 0 3

O: 3 0 0 0 O: 3 0 0 0

Al: 0 1 0 1 Al: 0 1 0 1

OH: 0 3 0 0 OH: 0 3 0 0

NO3: 0 0 3 0 NO3: 0 0 3 0

We can use the Gauss-Jordan method to reduce the matrix to its row echelon form, by performing row operations that do not change the solution. We begin with the upper-left corner element (H) as the pivot element, and use row operations (addition and subtraction of rows) to reduce all other elements in the column below the pivot to zero.

We repeat this process for each column until the matrix is in row echelon form. First, we subtract row 1 from rows 2 and 3 to eliminate the “H” coefficient in those rows.

H: 1 0 3 0 H: 1 0 3 0

N: 0 0 -3 3 N: 0 0 -3 3

O: 0 0 -9 0 O: 0 0 -9 0

Al: 0 1 0 1 Al: 0 1 0 1

OH: 0 3 0 0 OH: 0 3 0 0

NO3: 0 0 3 0 NO3: 0 0 3 0

Then, we add row 2 to row 3 to eliminate the “N” coefficient in row 3. H: 1 0 3 0 H: 1 0 3 0

N: 0 0 -3 3 N: 0 0 -3 3

O: 0 0 0 3 O: 0 0 0 3

Al: 0 1 0 1 Al: 0 1 0 1

OH: 0 3 0 0 OH: 0 3 0 0

NO3: 0 0 3 0 NO3: 0 0 3 0

We can now solve for the coefficients by reading the values on the left side of the matrix:

HNO3: 3

Al(OH)3: 1

Al(NO3)3: 1

H2O: 3

Therefore, the balanced equation for HNO3 + Al(OH)3 is:

3HNO3 + Al(OH)3 Al(NO3)3 + 3H2O
