    Caustic Difference
Click For Summary
Caustic soda and caustic potash are distinct chemical compounds with different formulas: sodium hydroxide (NaOH) for caustic soda and potassium hydroxide (KOH) for caustic potash. The primary difference lies in their constituent elements; sodium (Na) in caustic soda and potassium (K) in caustic potash. Both compounds are strong bases, but they differ in their chemical properties and applications. The name "sodium hydroxide" is correct for NaOH, clarifying that it is not a typo. Understanding these differences is crucial for their appropriate use in various chemical processes.

I read the chemical formula for Potassium Hydroxide (Caustic soda)=NaOH (1)I also read the chemical formula for caustic potash having same chemical name Potassium Hydroxide =KOH.

I want to know what is the difference between these two chemical compounds in terms atoms, molecules, ions? Why the name of (1) is not Sodium Hydroxide as it contains sodium(Na)?

It looks like a typo in your book. The name of $\ce{NaOH}$ is indeed Sodium Hydroxide, also known as lye and caustic soda.
 

Thread 'Significant figures for inherently bound values'

I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
