Indra : hay iin. .
Iin : hy too
Indra : do you have a lot of free time?
Iin : yes, what is it?
Indra : I want to ask chemistry lessons about acids and
bases, because I do not understand much about them either
Iin : ok, just please, as I know then I will reply.
Indra : when acid and base are reacted there will be a neutralizing
reaction of the substance whether it will be formed?
Iin : of course the reaction result is salt and water.
Indra : so salt and water to be formed, So it is.
Indra : then when the blue and blue litmus are input into the acid
or base solution how does it change?
Iin : the blue lacmus will turn red when input to the acid
solution, but the red litmus remains. While the red litmus will turn to blue when
inserted into the alkaline solution, but the blue lacquer remains.
Indra : ok now I understand, trimaksih iin for his explanation.
Iin : thanks again senses
What is the meaning about chemistry lessons about acids and bases?
BalasHapus
BalasHapusAcids and bases are basic knowledge in chemistry, we should understand about acid and base well.
How to determine the cause of a reaction and the effect of a reaction?
BalasHapusThere are some things that can generally trigger skin allergies include:
HapusCosmetic products; Such as facial makeup, lotion, deodorant, soap, shampoo, and hair dye.
Cleaning products; Such as floor cleaners, laundry soap, disinfectants and the like.
Medicines applied to the skin, such as antigatal creams or antibiotics.
Accessories made of metal, such as nickel or gold.
Plants, may include leaves, stems, or pollen.
Latex, the material used for rubber gloves, condoms and balloons.
Insect spray.
Perfume.
Explain the examples of acids and bases
BalasHapusAcid is a compound that has a sour taste, while a base is a compound that has a bitter taste
HapusHow a solution can be said to be acid, base and neutral. Try to explain
BalasHapusThe solution is said to be sam if it has PH below 7, when using paperlakmus indicator then blue litmus paper will turn red, while red litmus paper remain. Then the solution is said to be alkaline if it has PH above 7, and when using litmus paper indicator it will brighten red litmus paper while blue litmus paper remains. And the solution is said to be neutral if PH = 7, if using litmus paper as an indicator then it will not change both.
HapusWhat is the reaction result of weak acid with weak base?
BalasHapusReaksi yang terjadi adalah hidrolisis total. Hidrolisis garam yang berasal dari asam lemah dan basa lemah merupakan hidrolisis total, sebab kedua ion garam mengandung hidrolisis dengan udara. Sifatnya ditentukan oleh harga tertapan kesetimbangan asam (Ka) dan tetapan kesetimbangan basa (Kb) dari kedua reaksi tersebut. PH larutan garam yang berasal dari asam lemah dan basa lemah secara kuantitatif dengan harga Ka dan Kb atau dengan konsentrasi garam. PH larutan hanya dapat ditentukan secara tepat.
