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.

When you add more detergent in the washing machine is the solution of water and detergent more dilute or concentrated?
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.
Which common minerals fizzes when dilute hydrochloric acid HCI is placed on it?
Asked by Wiki User
Calcite, Limestone, Chalk, Marble.
They are all geological forms of calcium carbonate.
What is the symbol equation for hydrochloric acid reacting with calcium carbonate?
Asked by Wiki User
Here is the BALANCED symbol reaction Eq'n.
2HCl(aq) + CaCO3(s) = CaCl2(aq) + H2O(l) + CO2(g)
In words; Two moles of hydrochloric Acid (HCl) reacts with one mole of calcium carbonate (CaCO3) to produce one mole of calcium chloride(CaCl2), one mole of water(H2O), and one mole of carbon dioxide(CO2).
Further symbols ;-
(aq) = aqueous ( in solution).
(s) = solid
(l) = liquid
NB for all acid and carbonate reactions, the products are a 'salt' , water and carbon dioxide.
(g) = gas.
What is the common name of citic acid?
Asked by Wiki User
What is 'citic acid'. Do you mean 'Citric Acid'?
However, the IUPAC name is 1-hydroxypropane-1,2,3-trioic acid'.
Is HC2H3O2 a base?
Asked by Wiki User
'HC2H3O2' is a rather poor way of writing the formula for ethanoic(acetic) acid.
It is usually written as 'CH3COOH'.
Calcium carbonate reacts with sulphuric acid?
Asked by Wiki User
YES!!!
It produces calcium sulphate, water and carbon dioxide.
Here is the balanced reaction equation.
- CaCO3(s) + H2SO4(aq) = CaSO4(s) + H2O(l) + CO2(g)
What will happen if the pH value in our body increases?
Asked by Wiki User
You will become ill.
As an example , if you indugle in too much alcoholic liquor , you are altering your pH.
A 'hangover' is the effect of altering the pH to a more basic (higher) pH number.
Is CH3COO an acid or a base?
Asked by Wiki User
Correctly written it is 'CH3COO^- ' it is a conjugate base.
It is named as Ethanoate ion or Acetate ion.
Is lime water the same as hydrochloric acid?
Asked by Wiki User
NO!!!! They are two different substances.
Hydrochloric Acid has the formula 'HCl'
Lime water is a suspension of calcoum hydroxide , whose formula is Ca(OH)2.
Is BeO basic?
Asked by Wiki User
It is amphoteric oxide. Be show exception to other group members due to its small size and high charge potential
Is hydrochloric an example of vinegar?
Asked by Wiki User
NO!!!
Hydrochloric Acid is a mineral acid. Formula is (HCl)
Vinegar is Ethanoic (Acetic) Acid a Carboxylic acid. Formula is (CH3COOH)
What salt is formed between hydrochloric acid and lead?
Asked by Wiki User
Lead chloride (PbCl2)
The equation is
Pb(s) + 2HCl(aq) = PbCl2(aq) + H2(g)
Which gas is produced when dilute hydrochloric acid is added to reactive metal?
Asked by Wiki User
Remember the general acid reaction eq'ns.
Acid + Alkali = Salt + Water
Acid + Base = Salt + Water
Acid + Metal = Salt +Hydrogen
Acid + Carbonate = Salt +Water + Carbon Dioxide.
So if you react hydrochloric ACID with a METAL it will produce the gas HYDROGEN.
What is the element symbol for acetic acid?
Asked by Wiki User
Acetic Acid does NOT have an elemental symbol.
It is a compound formed from carbon hydrogen and oxygen.
Its structure is CH3-C(=O)OH
Acetic Acid is the old and commerical name for the modern IUPAC name 'Ethanoic Acid'.
How do fire service neutralise a acid?
Asked by Wiki User
One possibility is powdered calcium carbonate.
Another is calcium hydroxide.
Is acetic acid is used in seasoning of food?
Asked by Wiki User
YES!!!
As vinegar, it can be put on fish and chips.
Acwric acid ,is the old commercial name for the modern IUPAC name 'Ethanoic Acid'.
It is the acid formed, when the alcohol ( ethyl alcohol/ethanol) in wine is oxidised, by being in contact with air too long.
Is Pyruvic acid an amino acid?
Asked by Wiki User
NO!!!
Pyruvic acid is a keto acid.
It has the structure
CH3 - C(=O) - COOH
Can an acid and a base react to form an acid?
Asked by Wiki User
NO!!!!
Remember the general acid reaction equations.
Acid + Base = Salt +Water
Acid +Alkali = Salt + Water
Acid +Metal = Salt + Hydrogen
Acid + Carbonate = Salt + Water + Carbon Dioxide.
NB An Alkali is a soluble Base.
Does limestone dissolved in acid?
Asked by Wiki User
YES!!!
Limestone is an impure form of calcium carbonate.
Calcium carbonate will react with acids to form the corresponding salt, water and carbon dioxide.
e.g.
CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(g)
Can stomach acid dissolve metal?
Asked by Wiki User
Stomach acid, which is primarily composed of hydrochloric acid, is not typically strong enough to dissolve metal. However, it can corrode certain metals over time. The stomach lining is designed to withstand the acidity, protecting the surrounding tissues.

What is the pH of 1.1 M HCl?
Asked by Wiki User
HCl fully disolvis to H^+ & Cl^-
Hence there are 1.1M of H^+ present and 1.1M of Cl^- present.
pH = -log(10) [ H^+]
In word, 'pH is the negative logarithm to the base ten of the hydrogen ion concentration.
Hence pH = -
pH =log(10)[1.1]
pH = -0.0413
pH =-4.13 x 10^-2
pH ~ 2.0
Is pH 9 a strong or weak acid?
Asked by Wiki User
A pH of 9 is not acidic, it is basic. in order to be acidic the pH must be less than 7
It does not show whether the base is strong or weak as pH depends on both the strength of the acid/base as well as its concentration.
