Acids and Bases

An acid is any substance whose aqueous solution is characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts. A Base is any substance whose aqueous solution is characterized by a bitter taste, a slippery feel, the ability to turn red litmus blue, and the ability to react with acids to form salts. Questions about the acidity and alkalinity of solutions and different types of acids and bases are found n our Acids and Bases category.

Is HOCl acidic?

User Avatar

Asked by Wiki User

HOCl is a weak acid that is formed when chlorine (a gas) dissolves in water. It is used as an active ingredient in sanitizers and disinfectants because of its ability to break apart cell membranes, similar to the mechanism of action of sodium hypochlorite (bleach) or hydrogen peroxide.

Why are there blue lines on notebook paper?

User Avatar

Asked by Wiki User

Blue lines on notebook paper serve as guides for writing, helping maintain consistent spacing and alignment. These lines assist in keeping handwriting neat and organized. The blue color is chosen for its visibility and contrast against the white paper, making it easier to see while writing. Search FashionTIY in Google.

Can alkaline based acids burn the eyes?

User Avatar

Asked by Wiki User

'What are 'Alkaline Based Acids'. ?????

Alkalis. Bases and Acids are three different types of chemicals.

However, burn or no burn , you do NOT put either chemical in you eyes. In the lab. you should be wearing goggles or specs/glasses with blinkers to protect your eyes. However, if you have any chemical splash into your eyes, wash immediately with plenty of water, go and see an Eye Doctor immediately.

You only put into your eyes, eye drops which are a mixture of chemical salts specially designed for eyes, and as directed by a doctor.

Are esters acidic?

User Avatar

Asked by Wiki User

NO!!! THey can be thought of as an organic salt.

To synthesis an ester you reflux an carboxylic(organic) acid and an alcohol, with a little mineral acid to act as a catalyst.

Here is the general equation

Acid + Alcohol = Ester + water.

An actual equation.

Propanoic Acid +Ethanol = Ethyl propanoate + Water.

CH3CH2COOH + CH3CH2OH CH3CH2COOCH2CH3 + H2O

Thid is a reversible reaction , and when the reactants are brought together , they will reach an equilibrium point, where all four components are in the reaction.

Is a carbonic acid weak or strong?

User Avatar

Asked by Wiki User

H2CO3 is a weak acid--you can tell because there is one less H than O. Strong ternary acids have at least 2 less H than O (for instance, H2SO4, HClO3, HClO4). Strong binary acids are made of halogens, except for weak HF (so they are HCl, HBr, HI).

What happens to Blue litmus paper if dipped in bleach?

nothing happens - just remain the same as long as it is pure alcohol. The chemical that makes the paper change colors reacts with acids and bases - but alcohol is neither.

Is shampoo an acid?

User Avatar

Asked by Wiki User

No, shampoo is not typically acidic. Most shampoos are formulated to be slightly alkaline, with a pH ranging from around 4.5 to 7.5. This pH range helps to cleanse the hair and scalp effectively while remaining gentle and avoiding irritation. Search Wholesale05 in Google.

How does the number of hydrogen ions compare to the number of hydroxide ions?

User Avatar

Asked by Wiki User

In pure water, at standard conditions, the number of hydrogen ions (H⁺) is equal to the number of hydroxide ions (OH⁻). This balance occurs due to the self-ionization of water molecules:

H

2

O

H

OH

H

2

O⇌H

+OH

For every water molecule that dissociates, one hydrogen ion (H⁺) and one hydroxide ion (OH⁻) are produced. The concentration of hydrogen ions (H⁺) is often denoted as [H⁺], and the concentration of hydroxide ions (OH⁻) is denoted as [OH⁻]. In neutral water (pH 7), these concentrations are equal:

[H+]=[H−]=10−7  mol/L [H+ ]=[OH− ]=10−7 mol/L

This balance ensures that the solution remains neutral. However, in acidic solutions, the concentration of hydrogen ions (H⁺) is higher than that of hydroxide ions (OH⁻), while in basic solutions, the concentration of hydroxide ions (OH⁻) is higher than that of hydrogen ions (H⁺). The product of the hydrogen ion concentration and the hydroxide ion concentration is always

10−14 mol 2 / L210−14 mol2 /L2

at 25°C, known as the ion product of water.

2 .What is the pH of the sodium hydroxide and hydrochloric acid mixture?

User Avatar

Asked by Wiki User

The pH of a mixture containing a strong base (sodium hydroxide) and a strong acid (hydrochloric acid) would depend on the proportions of the moles of acid and base added to the mixture. This would depend on the concentration of both the base and acid solutions and the quantities of the solutions added.

Is sulfuric acid an inorganic compound?

User Avatar

Asked by Wiki User

YES!!! REason ; It does NOT contain any carbon.

Sometimes it can be referred to as a minedral acid.

Other inorganic acids are

Hydrochloric acid

Nitric Acid

Phophoric Acid .

This list is NOT exhaustive. There are many more mineral acids.

However, There are the carboxylic acids, archaically (fatty acids). These are organic because they contain carbon.

Methanoic (formic) acid (HCOOH)

Ethanoic (Acetic) acid (CH3COOH)

Ethane-di-oic (Oxalic) acid (HOOC-COOH)

Pentanoic (Valeric) acid (CH3CH2CH2CH2COOH)

Again the list is not exhaustive . There are many more carboxylic acids.

What gas is reliced from Zn HCL?

User Avatar

Asked by Wiki User

First of all, to correct your English; 'reliced , should read 'released'.

The gas released is hydrogen .

Here is the balanced reaction equation.

Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)

This is the classic acid plus metal reaction.

Acid + metal = Salt + Hydrogen

Acid + Base = Salt + Water

Acid + Alkali = Salt + Water

Acid + Carbonate = Salt + Water + Carbon Dioxide.

NB An Alkali is a soluble Base.

Is sulfuric acid an acid or base?

User Avatar

Asked by Wiki User

By the very fact that it is named an 'acid', then it is an acid.

In the formula for acids , the hydrogen (H) is always the first letter.

H2SO4 Sulphuric Acid

HCl Hydrochloric Acid

HNO3 Nitric Acid

H3PO4 Phosphoric Acid

There are many more mineral acids

Soluble bases use the term 'hydroxide'. In the formula for hydroxides , the hydrogen comes last as ( -OH).

NaOH sodium Hydroxide

Ca(OH)2 Calcium Hydroxide

Al(OH)3 Aluminium Hydroxide

KOH Potassium Hydroxide

What is the pH of 5x10-4 hcl?

User Avatar

Asked by Wiki User

Remember pH = -(log(10)[H^+]

Substituting

pH = -(log(10)[5 x 10^(-4)]

On the calculator

pH - -(-3.30102996)

pH = 3.30 ( to 2 d.p.).

What is the pH of a solution that has a concentration of hydrochloric acid equal to 0.001 M?

User Avatar

Asked by Wiki User

Remembwer pH is = the negative logarithm to base ten, of the hydrogen ion concentration .

So with a concentration of 0.001 M

The hydrogen ion concentration is 0.001 = 10^(-3)

ph = -log(10)[H^+]

pH = -log(10)10^-3

pH = -(-3) log(10)10 ( Remember log(10)10 = 1 )

pH = -(-3)(1) = --3 = 3

pH = 3
