Why do many metal ions produce acidic solutions when dissolved in water?

Chemistry

<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>

In water solution, the conjugate base of HF is __________
anastassius [24]

Answer:

The correct answer is : F^-

Explanation:

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

Acid after donating protons changes into conjugate base and base after accepting protons changes into conjugate acid.

So, when HF in water reacts, it form fluoride ions and hydronium ions. The recation is given as:

HF+H_2O\rightarrow F^-+H_3O^+

Here, HF is acting as a  Bronsted Lowry acid by donating proton and forms it conjugate base F^-, Where as water is acting as a  Bronsted Lowry base by accepting a proton and forms its conjugate acid H_3O^+.

The calvin cycle and the krebs are referred to as cycles of chemical reactions because they
Schach [20]

Answer:

The options are

a. occur inside organelles. b. start over continually. c. are part of the carbon cycle. d. allow energy to flow in ecosystems.

The answer is b. Start over continually

Explanation:

The two cycles involves a continuous process as long as the reactants are present under suitable conditions. The cycle happens all the time due to it being necessary to produce important products all the time for the body system.

A good example involves the existing Carbon dioxide and water reacting together to get converted into substance that could provide energy (ATP and NADH) such as Glucose.

Write the balanced chemical equation for the reaction of khp with naoh
liubo4ka [24]

Answer:

KHP + NaOH ⟶ KNaP + H₂O

Explanation:

The H in KHP is the acidic hydrogen. The OH⁻ in NaOH neutralizes it  and converts it to H₂O.

The balanced equation for the reaction is

KHP + NaOH ⟶ KNaP + H₂O
