Is NaH basic or acidic?

Acid-Base Character For instance, in sodium hydride (NaH) the hydrogen has a -1 charge so it is not an acid but it is actually a base.

What is the pKa of CH3NH3Cl?

10.6
The pKa of methylamine [CH3NH3] is given as 10.6. This means that a salt of methylamine, such as CH3NH3Cl–, has an acidity constant Ka = 10-10.6, or 2.51 x 10-11.

What is the pKa of nh3?

38
The pKa of ammonia itself is 38, which measures the equilibrium constant for dissociation of NH3 to give its conjugate base, NH2(-) and H+.

Is pKa constant?

On the other hand, the pKa value is constant for each type of molecule. It is unaffected by concentration. Even a chemical ordinarily considered a base can have a pKa value because the terms “acids” and “bases” simply refer to whether a species will give up protons (acid) or remove them (base).

Is hydride a base?

The hydride ion in the saline hydrides is a strong base, and these hydrides react instantly and quantitatively with the hydrogen ion (H+) from water to produce hydrogen gas and the hydroxide ion in solution.

What is the pKa of ch3?

The pKa of acetic acid is 4.76. Acetic acid is a moderately weak acid; it dissociates partly when dissolved in water. Each pKa unit represents a 10-fold difference in acidity or basicity. The weaker an acid, the stronger is its conjugate base; the stronger an acid, the weaker is its conjugate base.

What is pKa value for sodium hydroxide?

Sodium hydroxide is a strong base with a 13.8 pKa value. Sodium hydroxide has a chemical formula of NaOH and is also referred to as lye or caustic soda. It is an organic compound and alkali salt .

What is sodium hydride used for?

Sodium hydroxide is the principal strong base used in the chemical industry. In bulk it is most often handled as an aqueous solution, since solutions are cheaper and easier to handle. Sodium hydroxide is also used for the manufacture of sodium salts and detergents, for pH regulation, and for organic synthesis.

What are common uses of sodium hydroxide?

Sodium hydroxide is used in drain and oven cleaners, chemical manufacturing, oil refining, hydraulic fracturing, water treatment and metal processing. It is also commonly used in the manufacture of fabric, plastic wrap, paper and soap , according to the Tennessee Department of Health.

What is the sodium hydride formula?

The formula of the chemical compound Sodium hydride is NaH
