The answer is 4 - .0001 equals 1X10 -4 which equals a pH of 4
Hydrocloric acid is a strong acid, so [H3O+] = 0.01 M.
pH = -log[H3O+] = -log(0.01) = 2.0
Since HCl is a strong acid .00001M HCl will produce a .00001M hydrogen ion concentration. Therefore, the pH will be 5.
pH = -log[H+] = -log(0.000001 + 10-7) = 5.96 = 6.0

It depends on what the solution is.

primary standard solution is prepared by direct measurements of the mass of solute and the volume of solution.whereas, a secondary standard solution is a solution whose concentration can't be determined directly from weight of solute and volume of solution, the concentration must be determined by analysis of the solution itself.
The pH is 6,15.

A solution is a homogenous mixture of two or more substances. while A solution whose concentration is known is called a standard solution.
2.5 x 10-2
This is an ionic compound dissociated in water.

Depends on the length the light traveled through the solution and the solution concentration. molar absorption = absorbance/(length x concentration) length is typically in cm and concentration is typically in mol/L
From areas of higher concentration (of water) to lower concentration (of water) - ie it fills the space. That would mean that it would flow from a solution whose concentration of solute is higher to one where the solute concentration is lower.
are any substances used to classify another, often by changing colour. A substance that's physical appearance is altered at or near the end of the reaction. A substance whose color varies depending on the concentration of hydrogen ions in the solution to which it is added to, also known as an indicator.
When a cell is placed in salt water it will shrink, but will swell in carbonated water. m.c
