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.

2khco3 + h2so4 ---> k2so4 + 2co2 + 2h20

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

Is 1 most acidic?

User Avatar

Asked by Wiki User

'1' what????

If you mean a pH of '1' , then yes!!! It is the most acidic. pH 14 is the least acidic/most alkaline.

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

Does diluting an alkali give a more concentrated solution?

Asked by Wiki User

NO!!! Dilution and concentration can be thought of as Chemical OPPOSITES.

What is the word equation for magnesium hydroxide neutralising hydrochloric acid in your stomach?

User Avatar

Asked by Karisteward

Milk of magnesia is magnesium hydroxide or Mg(OH)2 and is a base stomach acid is a dilute solution of hydrochloric acid or HCl, a strong acid.

They will react chemically to produce magnesium chloride an water.

MgOH + 2HCl --> MgCl2 + 2H2O

Are hemp hearts acidic or alkaline?

User Avatar

Asked by Wiki User

Hemp hearts are considered to be alkaline-forming in the body. While they contain a small amount of omega-6 fatty acids, which are generally associated with acidity, the overall composition of hemp hearts, including their high mineral content, tends to contribute to an alkaline environment when metabolized in the body. Therefore, incorporating hemp hearts into your diet can be part of maintaining a balanced and alkaline pH level.

Are acids neutralized by alkalis to make salts and water?

User Avatar

Asked by Wiki User

YES!!!

Here are the general equations for acid reactions.

ACID + ALKALI = Salt + Water

Acid + Base = Salt + Water.

Acid + Metal = Salt + Hydrogen

Acid + Carbonate = Salt + Water + Carbon Dioxide.

What does pH scale represent?

User Avatar

Asked by Wiki User

It represents the acidity of a substance.

0-6 being basic

7 is the most the neutral

8-14 is acidity

1= most basic of a substance

14= most acidic of a substance

What is 1-octanol and acetic acid reaction?

User Avatar

Asked by Wiki User

This is an ESTERification reaction.

CH3(CH2)6CH2OH + CH3COOH < ==H^+==> CH3COOCH2(CH2)6CH3 + H2O

The products are Octyl ethanoate(acetate) and water.

A little Sulphuric Acid (H^+) is used to speed up the relux reaction.

What is the name for the OH- ions?

User Avatar

Asked by Wiki User

'OH^-' ions are named as 'Hydroxides'.

e.g. Potassium hydroxide KOH. Calcium hydroxide 'Ca(OH)2'.

NB The hydroxide ion is ALWAYS written as 'OH'. Never' 'HO'.

NNB Being a negatively charged ion it correctly named as an 'ANION'.

What is a corrosive substance with a pH of less than 7.0?

User Avatar

Asked by Wiki User

pH is an indicator of acidity.

A substance registering a pH between 1 & 6 is Acidic (Possibly corrosive).ph of '7' is Neutrality e.g. water.

pH between 8 & 14 is Alkaline ( possibly corrosive).

pH is a logarithmic scale of the level of hydrogen ions in a substance.

Numerically larger the pH , then there are less hydrogen ions present.

When you add more detergent in the washing machine is the solution of water and detergent more dilute or concentrated?

User Avatar

Asked by Wiki User

Dilute solution because the amount of solute is a lot than the amount of solvent,we need a balance amount of water and detergent to dissolve it.

Does vinegar turn blue litmus paper red?

Asked by Wiki User

YES!!! Because vineger is a solution of ethanoic(acetic) acid.

What color forms when HCl is combined with NaOH?

User Avatar

Asked by Wiki User

This is a double displacement reaction. Abstractly, these reactions could be described in the following manner:

AB + CD --> AD + BC

Therefore, a neutralization reaction would look like this:

HCl + NaOH --> NaCl + H-OH

In other words, a neutralization reaction will always form water and a salt.
