comparison between acid and base


                                   acid 

                                 
1.  Acid is sour in taste,  Base is bitter in taste.

2.   Acid turns blue litmus to red,  Bases turns red litmus to  blue.

3.  Acis PH is  less than  7,  Base  PH is greater than  7. 

4.   It  is produces   H+ ion ( hydrogen ion) solution, Base  produces  OH ion  in  slution.

5.   Corrosive to metals,  Base is slippery to touch .

6.   React with  base  to form salt  and water, React with acid  to form salt and water.

7.  Example of acid- HCL, H2SO4.  Example of base NAOH,KOH.

8.  Conducts electricity in solution , in base  is also conducts electricity in   solution.

9.  Acid react  with  carbonates to  release CO2,  Base  does not  reacts with carbonates .

10.   Acid founds in citrus  fruits ( e.g-  Lemon ) Base found in soap  or detergents.

11.   Proton donors  ( Arrhenius  definition),  in Base -Proton  acceptor( Arrhenius definition).

12.   PH indicator-  Methyl orange  turns red, In base indicator -  Phenolphthalein turns pink .

13.  Used in batteries (e.g- Sulfuric acid ), Base  used in  antacids  ( e.g  magnesium hydroxide)

14.   Acid- Neutralizes  bases ,  base-  neutralized  Acid .

15.   Acids - Generally corrosive,  Base   can  be  caustic.

What are the factors that affects the degree of consolidation

Image
 Factor that affects the degree of consolidation . The degree of consolidation refers to the extent to which a soil or sediment has undergone a reduction in volume due to the expulsion of pore water under the influence of an applied load over time. Several factors affect the degree of consolidation. Below are the factors with detailed explanations: Magnitude of Applied Load The magnitude of the load applied to the soil directly influences the degree of consolidation. Explanation : When a load is applied to a soil layer, the increase in stress causes a rise in pore water pressure. Consolidation occurs as this excess pore water is expelled, and the soil particles rearrange into a denser configuration. Larger loads generate greater excess pore pressure, leading to a more significant volume reduction and a higher degree of consolidation. However, the soil's consolidation characteristics (e.g., compressibility) govern how the soil responds to the applied load. In over consolidated ...

how to control global warming .

Image
                     Global  warming how to control global warming. 1.rduce greenhouse gas. Emission the  most effective  way  to combat  global warming is to  reduce the emission of green house gases, especially  carbon dioxide(CO2)  methane (CH 4 ) nitrous oxide (N2 O) . This can be done  by  transitioning  to cleaner  energy  sources  like  solar , wind ,and  hydroelectric power. 2. Shift to renewable energy. By replacing  fossil fuels  like coal,oil, and natural gas  with  renewable  energy , we can significantly  reduce carbon emission . solar panels , wind turbines ,  and geothermal  energy provide  cleaner  alternatives  that generates  electricity without   polluting  the atmosphere. 3. Energy efficiency .  Improving energy  efficiency in building...

What are the main causes of global warming

Image
 What are the main causes of global warming . Global warming is primarily caused by human activities that increase the concentration of greenhouse gases (GHGs) in the atmosphere. These gases trap heat, leading to a rise in Earth's average temperature. Below are 15 main causes of global warming, explained in detail: 1. Burning of Fossil Fuels The combustion of fossil fuels like coal, oil, and natural gas for energy production is the largest contributor to global warming. This process releases massive amounts of carbon dioxide (CO₂) and other greenhouse gases into the atmosphere. Power plants, factories, and vehicles are the biggest sources of emissions. 2. Deforestation Trees absorb CO₂ from the atmosphere through photosynthesis, acting as carbon sinks. However, large-scale deforestation, especially in the Amazon rainforest and other tropical regions, reduces this capacity. When trees are cut down and burned, they release stored CO₂ back into the air,...
