When the pH drops from 7 to 5 the H plus concentration increases by 100 times. ie:for every drop back of pH by 1 unit the H plus concentration increases by 10 times.

According to the rate law how do concentration affect rate?
The rate will be dictated by the rate law. The concentration may have NO effect on rate in a zero order reaction, or it may be directly proportional to the concentration in a first order reaction. Also, in second order reaction, doubling the concentration will increase the rate by FOUR times.
What does it mean to say that ph scale is a log scale?
The pH scale is an inverse logarithmic representation of hydrogen proton (H+) concentration. Unlike linear scales, which have a constant relationship between the item being measured and the value reported, each individual pH unit is a factor of 10 different than the next higher or lower unit. For example, a change in pH from 1 to 2 represents a 10-fold decrease in H+ concentration, and a shift from 1 to 3 represents a one-hundred-fold decrease in H+ concentration.
When pressure increases the number of particles does what?
The volume stays the same if it is in a container. If it is not then the volume will increase.PV = nRTPressure times Volume = number of moles times Gas constant times temperatureThus if you raise temperature, pressure and/or volume must increase.
An acidic solution having a pH of 4 is how many times more acidic than a solution of pH9?
The pH scale represents a count of ions (hydrogen), or more accurately the "activity" of hydrogen ions. The pH is the negative of the logarithm (base 10) of the concentration in moles per liter. A solution with a pH of 4 is 100 times as concentrated as one with a pH of 6.
What relationship do you find between the pH number and the power of 10 used to express the H?
pH = -log10 [H+] So 0.001M = -log10 [H+] = 3 10 times higher concentration = 0.01M so -log10 [H+] = 2 The relationship is thus for every 1 unit of pH reduction there is a tenfold increase in concentration.
Does 15 times 3 increase or decrease?
15 x 3 = 45, so it is an increase.
What does ten fold mean?
it means an increase or decrease by 10 times.
What is the percent of decrease from 31 to 35?
If you mean percentage increase from 31 to 35 then it is as follows:- (35-31)/31 times 100 = 13% increase rounded to the nearest integer

How do you calculate a percentage change increase or decrease?
the new value minus the old value, then divide it by the old value, times 100%, if the value is positive, it's the percentage increase, if it's negative, it's the percentage decrease.
How do offices use ict?
Shops need to use ICT because some times to increase and decrease costs this will lower prices and increase profit

How can you increase the strength of an electromagnent?
2 things #1 increase the size of the magnet and the amount of times the wire is wrapped around the rod. #2 decrease the size of the wire and increase the power.
How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
How does the concentration of hydrogen ions vary with pH?
pH is the negative log of the hydrogen ion concentration. So lowering pH from 5 to 4 means a ten times increase in hydrogen ion concentration. Increasing pH by 1 results in decreasing hydrogen ion concentration to 1/10th its former level.
How can impulse be increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
