What is a true pH?
pH is a measure of acidity or alkalinity of a solution.
Is it true that Blue litmus paper stays blue when placed in an acid.?
Yes, that's true. Blue litmus paper remains blue when placed in an acidic solution because it is not sensitive to acids. Instead, it is red litmus paper that changes to red when exposed to an acid, indicating the presence of acidity.
What is one true way to tell you have a colloid solution?
One true way to identify a colloid solution is by observing the Tyndall effect, which occurs when light is scattered by the particles in the colloid. If you shine a beam of light through the solution and see a visible path of light, it indicates the presence of dispersed particles typical of a colloidal system. Additionally, colloids typically do not settle upon standing, distinguishing them from suspensions.
How you can prepare colliodal solution from true solution?
To prepare a colloidal solution from a true solution, you can add a dispersing medium (such as water) to the true solution. This will break down the solute particles in the true solution into smaller particles, forming a colloidal suspension. The interactions between the solute particles and the dispersing medium will stabilize the colloidal particles, preventing them from settling.
What is the difference between true and colloid solution?
Colloid is not a true solution they both differ from each other. Colloid is a kind of solution that scatters a beam of light passing through it and renders it path visible while a True solution is a kind of solution that scatters a beam of light passing through it and renders it path visible .
Is it true the lower the pH the higher the hydrogen ion concentration?
Yes, that is true. A lower pH indicates a higher concentration of hydrogen ions in a solution, while a higher pH indicates a lower concentration of hydrogen ions. pH is a measure of the acidity or basicity of a solution on a scale from 0 to 14.
What is a true pH?
pH is a measure of acidity or alkalinity of a solution.
Which of these statements is correct with respect to pH?
Some true statements regarding pH include, the pH scale indicates concentrations of hydrogen and hydroxyl ions in a solution. Anything above a pH level of 7.0 is basic, anything above a 7.0 is acidic, and a change in one pH unit denotes a ten-fold increase or decrease in hydroxyl ion concentration.
When Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates?
true altitude at field elevation.
Is it true the lower the pH means the greater number of hydrogen ions?
Yes, that is correct. A lower pH indicates a higher concentration of hydrogen ions in a solution, which means it is more acidic. pH is a measure of the concentration of hydrogen ions in a solution on a logarithmic scale.
Anything below pH 7 is acidic and above pH 7 is basic?
That's correct. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity or basicity. A pH of 7 is considered neutral.
Is HCI - H CI-- true of a base?
No, HCI- (Hydrogen Chloride) is a weak acid, not a base. It dissociates in water to form H+ and Cl- ions, contributing to the acidity of the solution.
Solution with a pH below 7?
A solution with a pH below 7 is considered acidic, meaning it has a higher concentration of hydrogen ions than hydroxide ions. This indicates that the solution has a higher acidity level and is below the neutral pH of 7. Examples of acidic solutions include lemon juice, vinegar, and gastric acid.
What is a graphic scale?
=(mapping) A graduated line that indicates the length of miles or kilometers as they appear on a map; the line has the advantage of remaining true after the map is enlarged or reduced in reproduction. Also known as bar scale. =

What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
What is always true about a chemical formula with H as the cation?
A chemical formula with H as the cation will always be acidic in nature because H cation represents a proton which can release in solution and contribute to acidity.
