The body's last and best defense against wide variations in blood pH is the?
Kidneys are the body's last and best defense against wide variations in blood pH. They regulate the levels of bicarbonate and hydrogen ions to maintain a stable pH in the blood.
What's the difference between alkalinity and pH levels in water?
Alkalinity measures the water's ability to resist changes in pH, while pH measures the acidity or basicity of the water. Alkalinity is a buffer against pH changes, while pH directly indicates the water's acid or base level.
What is the difference between pH and alkalinity in water chemistry?
pH measures the acidity or basicity of water, while alkalinity measures the water's ability to resist changes in pH. pH is a scale from 0 to 14, with lower numbers indicating acidity and higher numbers indicating alkalinity. Alkalinity is a measure of the water's buffering capacity against changes in pH.
What is meant by the term alkalinity?
Alkalinity refers to the ability of a solution to buffer against changes in pH when an acid is added. It is a measure of the concentration of alkaline compounds, such as bicarbonates, in the solution. Higher alkalinity levels indicate greater resistance to pH changes.
What changes the pH levels of soaps?
The pH depends on the ingredients.
What is the chemical used to identify changes in pH?
The chemical commonly used to identify changes in pH is an indicator, such as litmus paper or phenolphthalein. These indicators change color in response to changes in the acidity or alkalinity of a solution, allowing for easy visual detection of pH changes.
Can i use phenolphethalein for EDTA against calcium chloride?
No, phenolphthalein is not suitable for titrating EDTA against calcium chloride because phenolphthalein is a pH indicator that changes color when the pH of a solution changes, while the reaction between EDTA and calcium ions does not involve a significant change in pH. Instead, a different indicator like Eriochrome Black T is commonly used in complexometric titrations involving EDTA and metal ions like calcium.
What name is given to substance that resist changes in pH?
A substance which resists changes in pH is called a buffer.
Why is it so important for cells to buffer solutions against rapid changes in pH?
Cells require a stable pH for optimal functioning of enzymes and other proteins. Rapid changes in pH can disrupt the structure and activity of these biomolecules, leading to cellular dysfunction or even cell death. Buffering solutions help maintain a relatively constant pH by absorbing or releasing H+ ions in response to changes in pH, providing a stable environment for cellular processes.
What is it called when a substance changes color in response to pH?
This is a pH indicator.
Where is the secondary respiratory center found?
The secondary respiratory center is found in the medulla oblongata, which is part of the brainstem. It helps regulate respiration in response to changes in blood pH, oxygen levels, and carbon dioxide levels.
A scientist wants to test how much of a base can be added to a solution before the pH of the solution changes to above a certain point. The starting pH of the solution is 7.0 and the sc?
The scientist should begin by gradually adding the base to the solution while continuously measuring the pH. This process can be done using a pH meter or pH indicator to ensure accurate readings. The point at which the pH exceeds the predetermined threshold will indicate the maximum amount of base that can be added without surpassing that pH level. It may also be useful to plot the pH changes against the amount of base added for a clearer understanding of the relationship.
