No, the amount of rust is determined by the amount of available oxygen.
The pH will affect the rate of the formation of the rust, not the ultimate amount.
yes. It takes oxygen to oxidize metal (rust) and if your pH level of water is either Alkali or acidic then you wont get rust. A different type of oxidation takes place
What else can I help you with?
How hould you demonstrate that elodea carries out photosynthesis at a faster rate than it carries out respiration?
Do a pH test. The more CO2 consumed (photosynthesizing) the higher the pH. The more CO2 produced (Respiring) the lower the pH. And if a plant is photosynthesizing and respiring at the same rate, the pH will remain level. During a lab like this, we used bromothymol blue to test the pH levels. It will turn yellow if pH <7, blue if pH >7, and Green as the solution changes from acid to base or base to acid.
Would increasing cytoplasmic pH decrease the rate of sucrose transport into the cell?
No, increasing cytoplasmic pH would not decrease the rate of sucrose transport into the cell. Sucrose transport is usually driven by specific transport proteins that are not pH-dependent. However, extreme changes in pH could potentially affect the overall functioning of the cell and its transport processes.
How does the temperature affect the pH of vinegar?
Temperature can affect the pH of vinegar by influencing the rate of chemical reactions in the solution. Higher temperatures can increase the rate of reactions, potentially affecting the equilibrium between acidic and basic components in vinegar and thus the pH. However, the overall impact of temperature on pH may vary depending on the specific conditions and concentrations of the components in the vinegar solution.
How do you work out the rate of reaction when your independent variable is pH and your timing in seconds?
It is irrelevant what the independent variable is, whenever you work out rate of reaction you also divide 1 by the time in seconds. For example if it took 100 seconds your rate would be 0.01s-1.
Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme pepsin shows the greatest change in its rate of action with the least change in pH. Pepsin works optimally at a highly acidic pH of around 2, and even small changes in pH can significantly impact its activity.
What is a hypothesis for how pH in water Affects Copper Corrosion?
If the water's pH is more acidic (lower pH) then the effects of copper corrosion will be faster and more pronounce. If the water is less acidic (Higher pH) copper corrosion will take longer and be less pronounce.
Can copper turning be used to test how pH affects copper corrosion?
Yes, copper turning can be used as a test specimen to observe the effects of pH on copper corrosion. By subjecting copper turnings to different pH solutions and monitoring the rate of corrosion, one can determine how pH influences the corrosion of copper. This experiment can help in understanding the behavior of copper in different environments.
Why would a metal corrode more quickly in a salt water than distilled water?
In a medium of lower pH (acidic), the rate of corrosion is high. If the pH of medium is below 3 (approximately), even in absence of air severe corrosion takes place due to rapid evolution of hydrogen at cathodic areas, facilitating anodic oxidation of the metal and dissociation of corrosion product, exposing fresh metal surface for corrosion. In distilled water (pH about 7), rate of corrosion is relatively lower.
How does pH's of different liquids effect metal nails?
The pH of different liquids can affect metal nails by causing them to corrode or rust at a faster or slower rate. Low pH liquids (acidic) can accelerate corrosion of metal nails, while high pH liquids (alkaline) may have a protective effect or inhibit corrosion. The severity of the effect will depend on the specific pH level and chemical composition of the liquid.
What makes the corrosion rate higher in industrial areas than in urban areas?
Taking a look at the industrial areas,the corrosion rate seems to be higher since the industrial area can be said to be a combination of both an urban centre and a rural centre and invariably has a corrosion rate= corrosion rate of urban + corrosion rate of rural areas
Why does corrosion rate of no value on localized corrosion?
in my opinion, the value of corrosion rate obtained from certain reading is generally determine general corrosion rate, regardless what type of corrosion occur on a specific surface. in localized corrosion, where only some spots on surface is exposed to corrosion and other may be covered by film and etc. From my time of study, still didn't fine any research that can determine corrosion rate of localized corrosion unless u have a really micro- instrumentation that can monitor corrosion on the localized spots..

What are the condition required corrosion to take place?
Corrosion requires the presence of a metal, an electrolyte (usually water), and oxygen. Additionally, the metal must be in contact with another metal or material with different electrochemical properties, leading to the flow of electrons and the corrosion process. Temperature, pH, and other environmental factors can also affect the rate and extent of corrosion.
Is a pH level of 9.5 corrosive to aluminum?
Yes, a pH level of 9.5 is considered alkaline and can cause corrosion to aluminum over time. Aluminum is more susceptible to corrosion at higher pH levels, with the risk increasing as the pH level rises. It is recommended to avoid prolonged exposure of aluminum to alkaline solutions to prevent corrosion.
Why would you want to control the rate of corrosion?
You would want to control the rate of corrosion for an object in order to extend the life of that object and/or to be able to observe the corrosion in a controlled situation.
What is the relation between pK and pH?
At half equivalence (half neutralisation) pH=pK.
How does cirtric acid affect metals?
Citric acid can act as a chelating agent, forming complexes with metal ions. This can result in the dissolution of the metal surface, leading to corrosion or rusting. The rate of corrosion depends on factors such as concentration of citric acid, pH, and temperature.
What affects the rate of corrosion on a metal?
Factors that affect the rate of corrosion on a metal include exposure to moisture, presence of certain chemicals or pollutants in the environment, temperature variations, and the composition of the metal itself. Other factors such as pH levels, electrical conductivity, and the presence of oxides can also influence the rate of corrosion.
