What color does an acid and a base turn litmus paper? If the chemical or liquid is a base it will turn the paper blue and if it is an acid it will turn it red Edit
The Gradient. The gradient is a vector operation which operates on a scalar function to produce a vector whose magnitude is the maximum rate of change of the function at the point of the gradient and which is pointed in the direction of that maximum rate of change.In rectangular coordinates the gradient of function f(x,y,z) is:If S is a surface of constant value for the function f(x,y,z) then the gradient on the surface defines a vector which is normal to the surface. ApplicationsConduction heat transfer.f S is a surface of constant value for the function f(x,y,z) then the gradient on the surface defines a vector which is normal to the surface. ApplicationsConduction heat transfer.
Concentration gradient is defined as the variation in the concentration of solute, from one region to another, in a solution. While studying the movement of particles in a medium, you may come across various chemistry terms. To mention a few, such terms include concentration gradient, diffusion and osmosis.
