WebDec 30, 2024 · Sodium nitrate (NaNO 3) is a neutral salt. It is formed from the strong base (NaOH) and strong acid (HNO 3) reaction. NaNO 3 doesn’t attain any properties of acidic or alkaline on dissolving in an aqueous solution. Sodium nitrate is made from the neutralization of a strong base (NaOH) with a strong acid (HNO 3 ). It has a pH value equal to 7. WebThe most common oxidation states for Cr are 0, +3 and +6. Chromium is most commonly found in the +3 state, which is fortunate since the +3 state is considered benign as opposed to the +6 that is toxic. At Inorganic Ventures we note the oxidation state of chromium in a given CRM by writing Cr +3 or Cr +6.
