which increases the pH level of the solution towards 7, making it less acidic. However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is not alkaline.
Multiply the Kb value by the total ammonia concentration and the number 4. The total concentration is the sum of [NH4+] and [NH3] in the solution. This concentration must be known or given in order to calculate pH. For example, the concentration is equal to 0.1 molar. Then the value i...

The most accurate way to calculate the value of a college degree is to conduct a net present value (NPV) calculation. In the NPV formula, all future cash flows (CF) over some holding period (N) are discounted back to the present using a rate of return (r). This rate of return (r)...
What is the p-value in statistics? The p-value (denoted p) for a set of data is the probability that the given data (or something even more unusual) would occur if the hypothesis being tested is not true. How do you find p-value from z-statistic? To calculate the p-value, first ...
In method 1, for the first row, we used the base as 10 and got the logarithm value 2. Here we also get the same value. So, we can be sure about the fact that in the LOG10 function, the base is already defined as 10. Read More: How to Calculate Antilog in Excel Method 3 –...
How to calculate the lifetime value of a customer Segment customers with RFM Determine average order value Figure out average purchase frequency Calculate customer value Multiply customer value by average lifetime value 1. Segment customers with RFM Before we dive into customer lifetime value, let...
How do I calculate uncertainties for pH and log? I'm doing an experiment where I measure the pH, then do a few calculations to get to the pKa value. But for this experiment, I need to include the uncertainties. The uncertainties for things like mL, temperature, etc, are simple enough,...
