Acids and Bases

YES!!!! THis is a classic carbonate /acid reaction.;

Chalk is an impure form of calcium carbonate.

So it will dissolve in acids to produce a salt, water, and carbon dioxide.

Here is the word equation.

Hydrochloric Acid + Calcium carbonate = calcium chloride m water, and carbon dioxide.

Here is the balanced reaction equation.

2HCl(aq) + CaCO3(s) = CaCl2(aq) + H2O(l) + CO2(g) .

The is NO such compound as ' MgCl '. The correct formula is ' MgCl2 '.

It is magnesium chloride. .

Compounds compsed of a metal cation and and acid anion are CHEMICAL SALTS . They are neither acid nor alkali.

For maintaining a healthy heart, I recommend eating a balanced diet that includes green vegetables, fresh fruits, oats, whole grains, dal, beans, and unsalted nuts like almonds and walnuts. Try to limit excess salt, fried foods, sugary drinks, and processed foods.

Along with a healthy diet, regular physical activity is important. A gentle Home Calisthenics Workout can include comfortable walking, light stretching, and simple body movements to support overall fitness.

However, people diagnosed with heart weakness or heart failure should consult their doctor before starting any workout. The exercise intensity and diet should be suitable for their medical condition.

Remember, a healthy lifestyle, proper rest, prescribed medication, and consistency all play an important role in maintaining good health

' KF ' is a chemical salt.

'KF' is potassium fluoride.

A chemical salt is neither an acid nor a base .

P4O10 is acidic.

NO!!!!

Grapefruit is an acidic compound.

It contains two acids. viz., Citric Acid, and Tartaric Acid.

Tartaric acid is the main acid responsible for the characteristic tart/sour taste of grapes.

By the very fact it is referred to as 'Acidic' , it is an 'ACID'.

Acidic substances typically taste sour or tart. The taste is often described as sharp, tangy, or biting, and can evoke a puckering sensation in the mouth. Examples of acidic substances include citrus fruits like lemons and vinegar.

This is ethanoic acid and is usually written as C2H4O2 , and structurally as CH3-COOH

NB When writing organic formula write all the 'C' first , then all the 'H' , then all the remaining elements in alphabetical order.

So HC2H3O2 does not mean a thing.

Nothing!!!!

Acetic Acid is the archaic name

Ethanoic Acid is the modern IUPAC name.

The structure is CH3COOH in both cases.

Casually, scientists still use use/say 'acetic acid. However, in formal published documents/research papers is it named as 'Ethanoic Acid'.

Use the Avogadro No. m which is 6,022 x 10^(23) atoms/molecules in one mole of a substance.

Hence in 9.62 moles , there are

9.62 x 6.022 x 10^(23) = 5.79.. x 10^(24) molecules.

sulfuric acid

At its simplest ;

Use litmus paper. ; it will show different shades of red depending on the strength of the acid. i

Use Universal Indicator (UI) ; it will show different shades of red depending on the strength of the acid. However, it is more sensitive than litmus paper.

Finally,, use a pH meter. It has an electronic probe. The dial on the meter will show '0' strongest acid to '6' weakest acid.

H2SO4 is NOT an element.

It contains in combination, three elements, viz., hydrogen(H) , sulphur(S) , and oxygen )O).

A COMPOUND!!!!!

Compounds are a combination of atoms of different elements.

H2SO4 has three different elements present.

H2SO4 is sulfuric acid

H2SO4 is Sulphuric Acid

Do NOT confuse with

H2SO3, which is Sulphurous Acid'.

Note the spelling., and the number of oxygens present. They are two different acids.

Sulfuric acid can form salts by reacting with metals, metal oxides, metal hydroxides or metal carbonates. Some common salts produced from sulfuric acid include sulfates such as sodium sulfate (Na2SO4), copper sulfate (CuSO4) and zinc sulfate (ZnSO4).

Gold and Platinum.

Gold can be made to react in 'aqua regia' .

Aqua regia' is an archaic name for a mixture of hydrochloric acid and nitric acid .

Platinum is used as electrodes in electrolysis owing to its unreactivity.

When sulfuric acid reacts with a metal, hydrogen gas is produced along with the corresponding metal sulfate. The reaction involves the displacement of hydrogen from the acid by the metal. The rate and intensity of the reaction depend on the reactivity of the metal with sulfuric acid.

The (chemical) salt is calcium chloride. ( CaCl2)

It's called a chemical reaction.

Word eq'n

Hydrochloric Acid + Calcium = calcium chloride + hydrogen.

Balanced reaction eq'n.

2HCl(aq) + Ca(s) = CaCl2(aq) + H2(g)

NB

General Acid reactions.

Acid + Alkali = Salt + Water

Acid + Base = Salt +Water

Acid + Metal = Salt + Hydrogen ( The above system).

Acid + Carbonate = Salt + Water + Carbon Dioxide.

When hydrochloric acid reacts with calcium chloride, it forms calcium chloride and hydrogen gas. The chemical equation for this reaction is: 2HCl + CaCl2 -> CaCl2 + H2. This reaction is a double displacement reaction.

Active ingredients are metals and carbonates.

Acid + Metal = Salt + Hydrogen(possibly bubbles)

Acid + Carbonate = Salt + Water + Carbon Dioxide (Definite bubbles).

NB Try at home a little experiment.

Vinegar + Baking Powder. bubbles will be released.

The actual reaction is .

Ethanoic(Acetic) Acid + Sodium hydrogen(bi)Carbonate = Sodium Ethanoate(Acetate) + Water + Carbon Dioxide(Effervescence/bubbles)_.

CH3COOH + NaHCO3 = CH3COONa + H2O + CO2
